The molar mass of hydrogen sulfide is:
M H2S = 1 + 1 + 32 = 34 grams / mol;
Let’s determine the amount of substance in 6.8 grams of hydrogen sulfide:
N H2S = 6.8 / 34 = 0.2 mol;
Under normal conditions, one mole of ideal gas takes up a volume of 22.4 liters.
The volume of hydrogen sulfide will be:
V H2S = 0.2 x 22.4 = 4.48 liters;
One mole contains 6.022 x 10 ^ 23 molecules.
The number of hydrogen sulfide molecules will be:
K H2S = 0.2 x 6.022 x 10 ^ 23 = 1.2044 x 10 ^ 23 molecules;
