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

Text Solution

Verified by Experts

Mass percentage of solute
`=("Mass of the solute ")/( "Mass of the solution ")xx100`
`=("Mass of the solute ")/(" Mass of the solute +Mass of the solvent ")xx100`
`=(45)/(45+180 ) xx 100 =(45)/(255)xx100`
Mass percentage of solute = 20%
