Question

Calculate the approximate volume of a 0.500 mol sample of gas at 15°C and a pressure of 1.10 atm.

Answer 1

Answer:

11.97 L

Explanation:

Given :

⇒ Number of moles, n = 0.5 mol

⇒ Temperature, T = 15 °C = 288 K

⇒ Pressure, P = 1.1 atm

Solving using Ideal Gas Equation :

⇒ PV = nRT

⇒ V = 0.5 × 8.314 × 288 / 1.1

⇒ V = 144 × 8.314 / 1.1

⇒ V = 1197.216 m³ = 11.97 L (approx.)

Answer 2

• T=15+273=298k
• P=1.1atm
• n=0.5mol

Apply ideal gas equation

• PV=nRT
• V=nRT/P
• V=0.5(8.314)(298)/1.1
• V=1126.16mL
• V=1.12L
