Henry's law is applicable for gas, it states that the amount of dissolved gas in a liquid is proportional to its partial pressure above the liquid.
We know that, formula of Henry law is
p=KH×χ
⇒ χ=

5×1.013×105

1.67×108

nCO3

500∕18

=

5×1.013

1.67×1000

nCO2=

5×1.013×500

1.67×18

nCO2=

Now, mass of CO2 dissolved =
