Question

If 1.00 mol of co2 gas at 350 k is confined to a volume of 400 cm3, find the pressure pideal of the gas using the ideal gas equation.

Answer 1

71.8 atm

Solution:

Data Given:

Number of Moles = n = 1.0 mol

Temperature = T = 350 K

Volume = V = 400 cm³ = 0.4 L

Gas Constant = R = 0.082057 atm.L.mol⁻¹.K⁻¹

Formula Used:

Ideal Gas Equation is given as,

P V = n R T

Solving for Pressure (P),

P = (n R T) ÷ V

Putting values,

P = (1.0 mol × 0.082057 atm.L.mol⁻¹.K⁻¹ × 350 K) ÷ 0.4 L

P = 71.8 atm
