How many molecules are in 5 moles of O2? A. 6.02 × 1024 B. 3.010 × 1024 C. 3.10 × 1024 D. 3.010 × 1023
Answers
There are b) 3.010 * 10 ^ 24 molecules in 5 moles of O2
What is mole ?
The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilograms of carbon 12 .
Number of moles = 5 moles
Number of molecules = ?
Avogadro's number = 6.022 * 10^23
Number of molecules in 5 moles of O2= number of moles * Avogadro's number
= 5 * 6.022 * 10^23
= 30. 10* 10 ^23 = 3.011 * 10 ^ 24 molecules
There are b) 3.010 * 10 ^ 24 molecules in 5 moles of O2

9/5 C + 32 = F Check for boiling points
5/9 (F - 32) = C
Example:
F = 9/5 C + 32 = 9/5 * 20 + 32 = 68 F
And deg K = C + 273
So 20 deg C = 293 deg K
Answer:
68 F and 293.16 K
Explanation:
T F= 1.8(20) + 32 = 68 F
TK= 20 +273.16 = 293.16 K

5) the law of energy conservation states that energy is neither created nor destroyed, therefore what happens is that you use energy and transform it into another type of energy,
Explanation:
4) This exercise is asked to give some examples of thermal and electrical energy transfer
the transfer of thermal energy occurs when we grasp a hot or cold body due to the difference in temperature between the body and us there is an exchange of heat, for example when drinking a cup of hot coffee there is a transfer of energy from the cup to the hand .
If we take a can of cold soda there is a transfer from hand to can.
Electrical transfer occurs, for example, when a current passes through a light bulb, it becomes incandescent and gives light.
In all modern electrical appliances there is transformation of electrical energy
5) the law of energy conservation states that energy is neither created nor destroyed, therefore what happens is that you use energy and transform it into another type of energy,
For example, when you lift a box, the potential energy of the box increases with height, but the energy of the person decreases because it does work that is negative.
In amusement park rides, the energy accumulated in one part of the game generally with height is transformed into energy of movement in another part of the game, but the total energy remains constant.

In this exercise you are asked to find the weight of the body.
Mass is a quantity that is invariant, it measures the same everywhere, the weight depends on where it is measured, a simple way to find the weight of a body is
W = g m
where g is the constant of the place, in this case we have the weight of the body on Mars and its mass which is constant on Earth and on Mars
