What do you mean by osmotic pressure?When a semipermeable membrane separates a solution from pure water, osmotic pressure is defined as the pressure that must be applied to the solution side to stop fluid movement.These colligative properties include reduced vapor pressure, increased boiling point, decreased freezing point, and increased osmotic pressure. As described in this module, this small set of properties is critical to many natural phenomena and technological applications.The pressure required to prevent water from diffusing through a membrane via osmosis is known as osmotic pressure. The concentration of the solute determines it. Water diffuses from the lower concentration area to the higher concentration area.Osmotic pressure is a 'colligative' property, like freezing point depression, which means that it depends on the number of particles in solution but not on their chemical identity.To learn more about : Osmotic pressure

A. 48.6g
B. 62.1 g
C. 27.5 g
D. 0.016g
E. 21.5g
Answers
PLS MARK BRAINLEIST IF IM RIGHT
As per the details given, 48.6 g are present in 0.885 moles of manganese. The correct option is A.
To determine the gram contained in a given number of moles, use the element's molar mass. Manganese (Mn) has a molar mass of roughly 54.94 g/mol.
To calculate the grammes in 0.885 moles of manganese, use the following formula:
moles of Mn × molar mass of Mn = mass of Mn in grams
On calculating it:
0.885 moles × 54.94 g/mol = 48.60 g
Therefore, the mass of manganese present in 0.885 moles of manganese is 48.60 grams.
Thus, the correct answer is A. 48.6g.

condensationExplanation:
Condensation is a process in which the evaporated liquid substance such as water vapor gets turned back to its liquid form water.
So, condensation is the process in which water vapor changes to liquid .600.0 ml of a 0.385 M solution of LiCl is diluted to 900.0 ml. What is the new concentration of the solution.
Answers
Taking into account the definition of dilution, the new concentration of the solution is 0.2567 M.
First of all, you have to know that dilution is the reduction in concentration of a chemical in a solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volumeof the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
Ci: initial concentration Vi: initial volume Cf: final concentration Vf: final volume
In this case, you know:
Ci= 0.385 M Vi= 600 mL= 0.600 L (being 1000 mL= 1 L) Cf= ? Vf= 900 mL= 0.900 LReplacing in the definition of dilution:
0.385 M× 0.600 L= Cf× 0.900 L
Solving:
Cf= (0.385 M× 0.600 L)÷ 0.900 L
Cf= 0.2567 M
In summary, the new concentration of the solution is 0.2567 M.

4. The cup is a volume widely used by cooks in the UAE. One cup is equivalent to 237 mL.
a. If 1 cup of olive oil has a mass of 216 g, what is the density of olive oil in kg/mL?
b. Convert the density from part A to kg/mL. Write your answer in scientific notation.
Answers
Taking into account the definition of density and scientific notation, the density of olive oil is 0.000911 [tex]\frac{kg}{mL}[/tex] or 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]
Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. That is, density is the relationship between the weight (mass) of a substance and the volume it occupies.
The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
[tex]density=\frac{mass}{volume}[/tex]
In this case, you know that:
mass= 216 g= 0.216 kg (being 1000 g= 1 kg)volume= 237 mLReplacing in the definition of density:
[tex]density=\frac{0.216 kg}{237 mL}[/tex]
Solving:
density= 0.000911 [tex]\frac{kg}{mL}[/tex]
On the other side, scientific notation is a quick way to represent a number using powers of base 10.
The numbers are written as a product:
a×10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number. n = a whole number, which is called an exponent or an order of magnitude. Represents the number of times the point decimal is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.In this case, the density expressed in scientific notation is: 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]
In summary, the density of olive oil is 0.000911 [tex]\frac{kg}{mL}[/tex] or 9.11×10⁻⁴[tex]\frac{kg}{mL}[/tex]

If you take 35 mL of solution from (#2c) and add 0.225 L of water what is the concentration of the resulting solution in (% v/v)? (hint: you must determine the final volume first)
HELP
Answers
We want to find the concentration of the resulting solution of mixing 35mL of a given solution and 0.225 L of water.
We will find that the concentration is 13.5%.
First, we need to write both of these in the same units.
We know that:
1000 mL = 1L
Then:
35 mL = 0.035 L
So when we mix the solution and the water we end with a total volume of:
V = 0.035L + 0.225L = 0.260L
The concentration of solution will be equal to the quotient between the volume of solution we used (0.035 L) and the total volume of the mixture (0.260L)
We will get:
Concentration = (0.035L)/(0.260L) = 0.135
Now to write it as a percentage, we only need to multiply this by 100%.
0.135*100% = 13.5%
This means that the mixture has a concentration of the 13.5%.

why does exercising causes the change in our body ( breathing/heart rate)
Answers
Answer:
Explanation:
The biggest change in the body caused by regular exercise is to muscle tissue. ... At the cellular level, exercise triggers the release of substances that dilate the blood vessels in the muscle, letting in more oxygen, says Prof Bradford. These are short-term effects, but deeper changes come with regular exercise.
Exercising causes changes in our body because we're working our muscles so there's more going on with us compared to when we're just laying down. We need more oxygen to go to our muscles so we breathe harder and more rapidly. Our heart also beats faster because it needs to pump more blood to the muscles that are being worked.
