Ideal Gas Law Name ___________
1) Given the following sets of values, calculate the unknown quantity.
a) P = 1.01 atm
V = ?
n = 0.00831 mol
T = 25°C
b) P = ?
V= 0.602 L
n = 0.00801 mol
T = 311 K
2) At what temperature would 2.10 moles of N2 gas have a pressure of 1.25 atm
and in a 25.0 L tank?
3) When filling a weather balloon with gas you have to consider that the gas will
expand greatly as it rises and the pressure decreases. Let’s say you put about
10.0 moles of He gas into a balloon that can inflate to hold 5000.0L. Currently,
the balloon is not full because of the high pressure on the ground. What is the
pressure when the balloon rises to a point where the temperature is -10.0°C
and the balloon has completely filled with the gas.
4) What volume is occupied by 5.03 g of O2 at 28°C and a pressure of 0.998atm?
5) Calculate the pressure in a 212 Liter tank containing 23.3 kg of argon gas at
25°C?
Answers: 1a) 0.20 L 1b) 0.340 atm 2) 181 K 3) 0.043 atm 4) 3.9 L 5) 67.3 atm
