Density of a gas is found to be `5.46g/dm^3` at `27^@C` at 2 bar pressure. What will be its density of STP?

Explanation

`d_1=(p_1M)/(RT_1),d_2=(p_2M)/(RT_2)`
`d_1/d_2=(p_1T_2)/(T_1p_2)(or)d_2=(d_1T_1p_2)/(p_1T_2)`
`d_1=5.46 gm dm^-3,T_1=300k`
`P_1=2 ba r,p_2=1 ba r`
`T_2=273.15k`
Substituting the values ,
`d_2=(5.46gdm^-3times300ktimes1b ar)/(2ba r times 273.15k)`
`=2.998approx3.8gdm^-3`
