The sulfur content of an ore is determined gravimetrically by reacting the ore with concentrated nitric acid and potassium chlor

katen-ka-za [31]

Answer:

13.92 %

Explanation:

Mass of $BaSO_4$ = 12.5221 g

Molar mass of $BaSO_4$ = 233.43 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{12.5221\ g}{233.43\ g/mol}$

Moles of $BaSO_4$ = 0.0536 moles

According to the given reaction,

$Ba^{2+}_{(aq)}+SO_4^{2-}_{(aq)}\rightarrow BaSO_4_{(s)}$

1 mole of $BaSO_4$ is formed from 1 mole of $SO_4^{2-}$

Thus,

0.0536 moles of $BaSO_4$ is formed from 0.0536 moles of $SO_4^{2-}$

Moles of $SO_4^{2-}$ = 0.0536 moles

Moles of sulfur in 1 mole $SO_4^{2-}$ = 1 mole

Moles of sulfur in 0.0536 mole $SO_4^{2-}$ = 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 % = $\frac{Mass\ of\ Sulfur}{Mass_{ore}}\times 100$ = $\frac{1.7187}{12.3430}\times 100$ = 13.92 %
