Question
Density of a gas is found to be 5.46 g/dm3 at 7°C at 2 bar pressure. What will be its density at STP?
Solution
We know,

For the same gas at different temperature and pressure,
...(1)
Initial conditions, STP conditions

Substituting the values, we have


For the same gas at different temperature and pressure,

Initial conditions, STP conditions

Substituting the values, we have
