Question

A solution is prepared by dissolving 45 g of sugar in 180 g of water. Calculate the mass percentage of solute.

Answer 1

Mass of the solute (sugar) = 45 g

Mass of the solvent (Water) = 180 g

Formula:

Mass percentage of solute (sugar) = `"Mass of the solute"/("Mass of the solute" + "Mass of the solvent") xx 100`

= `45/(45 + 180) xx 100`

= `45/225 xx 100 = 20%`

The mass percentage of solute = 20%
