HENRY'S LAW

I did the first one im not sure how to do the 2 and the 3rd question.


1. What is the Henry's law constant for
CO2 at 20{C}?

C=kP
K=c/p
= 3.70*10^-2/1.00atm= 0.037


2. What pressure is required to achieve
a CO2 concentration of 6.0010−2 at
20{C}?

Given: C (mol/L)= 6.0010−2
T(C)= 20C


3. At 1 atm, how many moles of CO2 are
released by raising the temperature
of 1 liter of water from 20{C} to 25
{C}?

Given: P(atm)= 1.00
k( mol/L.atm)= 3.4010−2
T= 25C
