# 2.7    Henry’s law constant for    in water is   at   Calculate the quantity of    in  of soda water when packed  under     pressure at

We know that ,

Pressure of CO =  2.5 atm

We know that :

So,   Pressure of CO2    =     Pa

By Henry Law we get,

Taking density of soda water = 1 g/ml

We get mass of water = 500 g.

So,                                Moles of water :

Also,

So,            moles of CO2  =  0.042 mol

Using relation of mole and given mass, we get

Mass of CO2  =   1.848 g.
