Given
m (H2S) 6.8g
To find
V (H2S)?
Decision.
We calculate the molar mass (according to the periodic table)
M (H2S) = 34 grams / mol.
n = m / M
n (H2S) = 6.8g: 34g / mol = 0.2 mol
n = v / Vm (molar volume, this is a constant equal to 22.4 liter / mol)
v = n ∗ Vm
v = 0.2 mol * 22.4 liter / mol = 4.48 liter
Answer: 4.48 L
