Answer:
n = 4678.13 mol
Explanation:
Given data:
Temperature = 21°C
Pressure = 746 mmHg
Volume = 115 m³
Number of moles = ?
Solution:
21+273 = 294 k
746 /760 = 0.982 atm
115×1000 = 115000 L
PV = nRT
n = PV/RT
n = 0.982 atm × 115000 L /0.0821 atm. L. K⁻¹. mol ⁻¹× 294 k
n = 112930 atm. L/24.14 atm. L. mol ⁻¹
n = 4678.13 mol
