The density of a gas at 675 mm pressure ...

The density of a gas at 675 mm pressure is `45gL^(-1)`. What is the density of the gas at 750mm pressure at the same temperature?

Text Solution

Verified by Experts

Given : `P_(1)= 675mm, d_(1)= 45, P_(2)= 750mm`
According to Boyle.s law `P propto (1)/(V)" "` [at constant temperature]
Density, `d= (m)/(V)" or "d propto (1)/(V)" or "P propto d" "` [when m is constant]
`(P_1)/(d_1)= (P_2)/(d_2) implies d_(2)= (P_(2)xx d_(1))/(P_1) = (750mm xx 45)/(675mm)= 50gL^(-1)`.
