Question

Calculate the volume occupied by 7g of nitrogen gas at 27degree celcius and 750mm of Hg pressure

Answer 1

Moles of Nitrogen = Weight / Molar mass
= 7 g / (28 g/mol)
= 0.25 mol

Pressure = 750 mm Hg
= (750/760) atm ………[∵ 1 atm = 760 mm Hg]
= 75/76 atm

From ideal gas equation
V = nRT/P
= (0.25 mol × 0.0821 atm.L / (mol K) × 300 K) / (75/76 atm)
= 6.2396 liters

Volume occupied by gas is 6.2396 liters
