The Henry's law constant for helium gas in water at 30°C is 3.70 x10-4 M/atm. If the partial pressure of helium above a sample of water is o.650 atm, what is the concentration of helium in water? 


A. 5.69 x10-4 M B. 1.76 103 M C. 1.30 M vD. 2.41 x10-4 M

Solutions

Expert Solution

henry's law constant kH = 3.70 x 10^-4 M / atm

partial pressure of He = 0.650 atm

concentration = kH x P

                      = 3.70 x 10^-4 x 0.650

                      = 2.41 x 10^-4 M

concentration = 2.41 x 10^-4 M
