Question

Calculate the volume occupied by 5 moles of a gas at 7°c
and a a pressure of 1 atm = 1.01x 10^5 N/m²​

Answer 1

Answer:

115 Litres

Explanation:

PV = nRT

V = nRT/p

Pressure (P) = 1.01 x 10^5 Pa

Number of moles (n) = 5 mol

Temperature (T in Kelvin) = 7 + 273 = 280 K

Universal Gas Constant (R) = 8.314 J/mol/K

Substituting these in the equation:

V = 5 x 8.314 x 280 / 1.01x10^5

   = 0.115 metre cube = 115 dm^3 = 115 litres
