The empirical formula of compound that contains 4. 03g of hydrogen per mole, 64. 14 g of sulfur per mole and 128 g of oxygen per mole is H₂SO₂.
given that :
mass of hydrogen = 4.03 g
mass of sulfur = 64.14 g
mass of oxygen = 128 g
moles of hydrogen = mass / molar mass
= 4.03 / 1
= 4mol
moles of sulfur = 64.14 / 32
= 2 mol
moles of oxygen = 128 / 32
= 4 mol
dividing by the smallest one , we get
mole of H = 2
mole of S = 1
mole of O = 2
The empirical formula = H₂SO₂
Thus, the empirical formula of compound that contains 4. 03g of hydrogen per mole, 64. 14 g of sulfur per mole and 128 g of oxygen per mole is H₂SO₂.
