Ответ:
n = 3.25 mol
Explanation:
Given data:
Pressure of sample = 2 atm
Volume of sample = 40 L
Temperature = 300 K
Number of moles = ?
Solution:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
2 atm ×40 L = n × 0.0821 atm.L/mol.K × 300 K
80 atm.L = n × 24.63 atm.L/mol
n = 80 atm.L /24.63 atm.L/mol
n = 3.25 mol
