Calculate the number of moles of hydrogen present in `500 cm^(3)` of a gas under a pressure of `101.3 ` kPA at a temperature of `300K`. (`R=8.314 J K^(-1) mol^(-1))`.

Text Solution

Verified by Experts

`n=?`
`PV= nRT " " V=500 cm^(3)`
`n=(PV)/(RT) " " =500xx10^(-3) dm^(3)`
`=(101.3xx0.5)/(8.314xx300) " " T=300K`
