A solution was prepared by dissolving 25 g of sugar in 100 g of water. Calculate the mass percentage of solute.

Answer»

Solution :Massof the SOLUTE = 25g
Mass of thesolvent= 100 G
Mass percentage = `( " Massof the solute")/("Mass of the solution ") xx 100`
Masspercentage=`( " Mass of thesolute ")/("Mass of the soluteof thesolvent ")xx 100`
`=(25 )/( 25+100 ) xx 100 =(25)/( 125 ) xx 100= 20 %`
