Calculate the mass fraction of hydrogen in hydrogen sulfide.
| April 9, 2021 | education
The molar mass of hydrogen is 2 grams / mol;
Let’s determine the molar mass of hydrogen sulfide:
M H2S = 1 x 2 + 32 = 34 grams / mol;
The mass fraction of hydrogen in hydrogen sulfide will be equal to the ratio of the molar mass of hydrogen to the molar mass of hydrogen sulfide.
K = M H2 / M H2S = 2/34 = 0.0588 = 5.88%;
