1.19g of volatile liquid gas on complete vaporisation gives 216ml of its vapour at `27^(@)` and 755 mm pressure. Calculate molar mass of liquid. `(R=0.082litatmK^(-)mol^(-))`

Text Solution

Verified by Experts

`w=1.19gm, M=?`
`P=(755)/(760)atm, V=(216)/(1000)lit, T=27^(@)=(273+27)=300K`
`thereforeM=(wTR)/(PV)=(1.19times0.082times300)/((755)/(760)times(216)/(1000))=(1.19times0.082times760times1000)/(755times216)=136.43`
`therefore` Molar mass of the liquid=136.43.
