Suppose Nitrogen Gas is acting Ideally, then According to Ideal Gas Equation, Pressure, Volume, moles and Temperature are related to each other as,
P V = n R T
Solving equation for V,
V = n R T / P ------- (1)
Data Given;
Volume to find = V = ?
Standard Pressure = P = 1 atm
Standard Temperature = T = 273 K
Moles Given = n = 0.355 mol
Putting values in eq.1,
V = (0.355 mol × 0.0821 atm.L.mol⁻¹.K⁻¹ × 273 K) ÷ 1 atm
V = 7.95 L
