Question

calculate the volume occupied by 2 moles of a gas at 7 c and a pressure 1 atm

Answer 1

Answer:

Explanation:

PV = nRT

V = nRT/p

Pressure (P) = 1 atm = 1.01 x 10^5 Pa

Number of moles (n) = 2 mol

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

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

Substituting these in the equation:

V = 2 x 8.314 x 280 / 1.01x10^5

  = 0.046 metre cube = 46 dm^3 = 46 litres
