Question

A tank of hydrogen gas has a volume of 22.9L and hold 12 mol of gas at 12°C what is the pressure of the gas in atmospheres?

Answer 1

P = 14.3 atm

Step-by-step explanation:

PV = nRT

T = 12 C + 273 = 285K

P = nRT/V

P = 14.0 mol H(0.08205 L * atm/mol * K)(285 K) / 22.9 K

mol, L, and K cancels out

P = 14.3 atm
