Question

Using the ideal gas law, determine the amount of gas, in moles, of a 8.32 L sample of hydrogen gas, under a temperature of 310 K and a pressure of 1.7 atm.

Answer 1

0.56 moles

Step-by-step explanation:

Ideal gas equation

PV = nRT

P = 1.7 atm

T = 310K

V = 8.32L

R = 0.08205 L atm / K.mol

PV = nRT

n = PV / RT

n = (1.7 * 8.32) / (0.08205 * 310)

n = 14.144 / 25.4355

n = 0.556

n = 0.56 moles
