40g of a gas occupies 20 dm3 at 300K and 100 kilopascal pressure. If the pressure is changed to 50 kilopascal without changing the temperature, what would be its volume?

That means the Temperature is constant.
Hence from ideal gas eqn. we get,
PV = nRT
100*20 = n*R*T
AND after changing pressure,
50*V = n*R*T
since both’s RHS is same.
PV = constant and hence  Boyle’s law is valid here.
Therefore,
100*20 = 50*V
V = 2000/50 => 40 dm3
