A vessel of 5 litre capacity maintained ...

A vessel of 5 litre capacity maintained at `27^(@)C" was filled with 16g of "O_(2)gas.` Calculate the pressure of the gas in atmospheres in the container.

Text Solution

Verified by Experts

Volume of gas = volume of container
V=5 litre
`T= 27^@C`
= 27 + 273
= 300 K
Give mass (m) = 16 g
Molar of mass of `O_(2) = 32 g`
`n= m/n = 16 / 32 =0.5 mol `
Pressure (P) = ?
Applying ideal gas equation PV = nRT
R= 0.0821 lire atm `K^(-1) mol^(-1)`
`P= (nRT)/(V)`
`=(0.5 xx 0.0821 xx 300) /( 5)`
`=2.46 amt `
