Question

If you have 4.7 moles of helium at a temperature of 37ºC and a pressure of 130kPa, what volume does this gas occupy?

Answer 1

Using Ideal Gas equation

PV = NRT

where , P = pressure of the gas

V = volume of the gas

N = number of moles of the gas

R = gas constant

T = temperature of the gas

substituting the given values in above mentioned ideal gas equation

130*1000*V = 4.7 * 8.314*(273+37)

Volume occupied by helium gas at given conditions = 0.0932 m^3 or 93.2 L
