Answer:
13.92 %
Explanation:
Mass of = 12.5221 g
Molar mass of = 233.43 g/mol
The formula for the calculation of moles is shown below:
Thus,
Moles of = 0.0536 moles
According to the given reaction,
1 mole of is formed from 1 mole of
Thus,
0.0536 moles of is formed from 0.0536 moles of
Moles of = 0.0536 moles
Moles of sulfur in 1 mole = 1 mole
Moles of sulfur in 0.0536 mole = 0.0536 mole
Molar mass of sulfur = 32.065 g/mol
Mass = Moles * Molar mass = 0.0536 * 32.065 g = 1.7187 g
Mass of ore = 12.3430 g
Mass % = =
= 13.92 %
