At fixed temperature and 600 mm pressure...

At fixed temperature and `600 mm` pressure, the density of a gas is `42`. At the same temperature and `700 mm` pressure, what is the density of the gas?

Text Solution

Verified by Experts

According to Boyle.s law,
`Pprop(1)/(V)` (at constant temperature)
Density, `d=("Mass (M)")/("Volume (V)")or dprop(1)/(V)`
Again, `Ppropd`
`therefore (P_(1))/(d_(1))=(P_(2))/(d_(2))`
Here, `P_(1)=600,d_(1)=42,P_(2)=700`
`therefore d_(2)=(P_(2)xxd_(1))/(P_(1))=(700xx42)/(600)=49`
