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