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.

1.77mg

Explanation:

Hello,

Since the Henry's constant is eligible for (hydrogen gas), its concentration into the 315 mL of water is given by:

Now, with the following factors, the mass in grams is found as:

Taking into account that the first parenthesis accounts for the concentration of , the second one for the volume of water, the third one for the molar mass of and the last one for the conversion from g of to mg of .

Best regards.

i'm wiling to try and you : )
