Question

The volume of given mass of a gas is 0.6 dm³ at a pressure of 101.325K Pa. Calculate the volume of the gas if its pressure is increased to 142.860KPa at the same temperature.​

Answer 1

according to ideal gas equation:

PV= nRT (since T is given as constant)

PV = constant

so

P¹V¹ = P²V²

101.325 * 0.6 = 142.860 * V²

V²= 101.325 *0.6 / 142.860

V² = 0.4255 dm³ or 0.4255 L ( 1dm³ = 1 L)
