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
