Calculate the volume (in cm3) that 4. 00 cm3 of gas at 30 oC will occupy at 130oC when the pressure is kept constant
Answers
The volume of the gas is 5.32 cm³.
To calculate the volume of the gas, we use Charles' law.
Charles' lawCharles' law states that at constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature. This can be expressed mathematically as
Formula:
V/T = V'/T'............. Equation 1Where:
V = Initial volume of the gasV' = Final volume of the gasT = Initial temperature of the gasT' = Final temperature of the gas.Make V' the subject of the equation.
V' = VT'/T......... Equation 2From the question,
Given:
V = 4 cm³T = 30 °C = 303 KT' = 130 °C = 403 KSubstitute these values into equation 2
V' = (4×403)/303V' = 5.32 cm³Hence, the volume of the gas is 5.32 cm³.

What is the molarity of a methanol solution produced when 0.2 L of a 3 M solution was diluted to 0.8 L?
A-0.2M
B- 0.4M
C-0.75M
D-0.8M
Answers
The molarity of the methanol solution produced at the given number of moles and volume is 0.75 M.
Molarity of the methanolThe molarity of the methanol is determined from the ratio of the number of moles of the methanol to the volume of the methanol.
The molarity of the methanol is calculated as follows;
Molarity = moles/volume
moles = 0.2 L x 3 M = 0.6 mole
Molarity = 0.6 mol/0.8 L
Molarity = 0.75 M
Thus, the molarity of the methanol solution produced at the given number of moles and volume is 0.75 M.

1. As you increase the temperature of a gas in a sealed, rigid con-
tainer, what happens to the density of the gas? Would the results
be the same if you did the same experiment in a container with
a movable piston at a constant external pressure? Explain.
Answers
Answer:
If one increases the temperature of a gas in a sealed, rigid container, the density of gas will not change.
The key to this answer lays in the ideal gas equation:
pV = nRT
Thus, one can write: n = (m)/(M)where m is the mass of the gas and M is the molar mass of a gas.
pV = (m)/(M) RT
Hence, if one decides to divide the entire equation with volume, V, one may write:
p = (m)/(VM) RT
ρ = (m)/(V), where ρ is density
p = (ρ)/(M) RT
If one increases the temperature, in order to keep balance, the pressure will be increased, also. Container is rigid, so that means the volume is constant.
However, this will not affect the density because there is no difference in volume (V = const.) or the amount of gas (n = const).
If one had a container with a piston, yet, constant pressure, the change of the temperature will impact the density.

For a gaseous reaction, N2 + 3H2 gives 2NH3. If 20 ml of nitrogen completely reacts with hydrogen, then what is the volume of produced NH3?
Answers
N2(g) + 3H2(g) → 2NH3(g)
20ml of nitrogen
to find:the volume of produced NH3
solution:So, 1 volume of nitrogen gas reacts with 3 volumes of hydrogen gas to produce 2 volumes of ammonia gas.
For this gaseous reaction in which all the reactants and products are gases we could write a chemical equation:
1 volume N2(g) + 3 volumes H2(g) → 2 volumes NH3(g)
1 volume of N2 is 20 ml so 2 volume of NH3 will be 40 ml .
Then , 20 ml N2 will give 40 ml of NH3
