What mass of hydrogen gas, in mg, is dissolved in 3.15×102 ml of water when the partial pressure of hydrogen above the water is 3.6 atm at 25 °c? the henry's constant for hydrogen gas in water at 25 °c is 7.8×10-4 m/atm.
Answers: 3
(hydrogen gas), its concentration into the 315 mL of water is given by:
![m=(2.808x10^{-3} \frac{mol H_{2}}{L} )*(0.315L)*(\frac{2g H_{2} }{1 mol H_{2}} )*(\frac{1000 mg H_{2}}{1 g H_{2}} )[tex]m=1.77 mg H_{2}](/tpl/images/0241/1577/7964b.png)
