Orlov [11]

Answer:

n = 0.34 mol

Explanation:

Given data:

Given temperature = 789 K

Pressure = 765 torr ( 765/760 = 1.0 atm

Volume of container = 22.0 L

Number of moles of gas = ?

Solution:

Formula:

PV = nRT

n = PV/RT

n = 1.0 atm × 22.0 L / 0.0821 atm.L/mol.K ×789 K

n = 22.0 L.atm /64.8 atm.L/mol

n = 0.34 mol
