Question

A rigid vessel filled to 0.8 of its volume with liquid nitrogen at its normal boiling point is allowed to warm to 25°C. What pressure is developed? The molar volume of liquid nitrogen at its normal boiling point is 34.7 cm3·mol–1.

Answer 1

704.25 atm

Step-by-step explanation:

From the ideal gas equation

PV = nRT

P = nRT/V

Molar volume (V/n) = 34.7 cm^3/mol, n/V = 1/34.7 = 0.0288 mol/cm^3

R = 82.057 cm^3.atm/mol.K

T = 25°C = 25+273 = 298 K

P = 0.0288 × 82.057 × 298 = 704.25 atm
