In the following, what is the unknown variable:
What is the volume of a balloon if it contains 3.2 moles of helium at a temperature of 20⁰C and 1.2 atm?
P
V
n
T
What is the correct value for T in the following problem:
What pressure is required to contain 0.023 moles of nitrogen gas in a 4.2 L container at a temperature of 20⁰C?
T = 0.23 K
T = 293 K
T = 4.2⁰C
T = 20⁰C
In the ideal gas law, P = (a) , V = (b) , n = (c) ,

Choose the correct set of variables to solve the following problem:
At what temperature would 4.0 moles of hydrogen gas in a 100 liter container exert a pressure of 1.00 atmospheres?
P = x (unknown), V = 1.0 atm, n = 100 L, R = 8.314 L·kPa/mol·K, T = 4.0 mol
P = 100 L, V = 4.00 mol, n = x (unknown), R = 0.0821 L·atm/mol·K, T = 1.00 atm
P = 4.00 mol, V = x (unknown) , n = 1.0 atm, R = 8.314 L·kPa/mol·K, T = 100 K
P = 1.00 atm, V = 100 L , n = 4.0 mol, R = 0.0821 L·atm/mol·K, T = x (unknown)
