Expert Answer

Step 1

Given:

Henry’s law constant for methane(CH4)=1.4x10-3 M/atm

Volume of water=625 mL

Partial pressure of methane=2.98 atm

Temperature=25 degree Celsius

Conversion:

From mL to L:

Volume of water=625 mL

                              =625/1000

                              =0.625 L

Step 2

Henry’s law expression is given as

CCH,KPCH
where CCH is concentration of methane
Kis Henry's law constant
P, is partial pres sure of methane
