Question:
Density of a gas is found to be 5.46 g/dm³ at 27 °C at 2 bar pressure. What will be its density at STP?

Answer:

For an ideal gas

Density ρ = p x M/ RT

F rom the given data,

5.46 = 2 x M/ 300 x R ………(1)

ALSO ρ_STP = 1 x M/ 273 x R ………..(2)

FROM (1) & (2) ,WE GET

ρ_{STP =}(1 x M/ 273 x R) x (300 x R/ 2 x M) x 5.46

= 300 x 5.46 / 273 X 2 = 3.00 g/dm³

Hence, the density of the gas at STP will be 3 g dm^–3.
