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
Answer:
0.209
