There are #"32.7 g KCl"# in #"100 g of solution"#.

#"(%w/w)"=("mass of solute")/("total mass of solution")xx100%"#

#"32.7% KCl( w/w)"=("mass KCl")/(100"g")xx100%#

Divide both sides by #100%#.

#"0.327 KCl"=("mass KCl")/(100"g")#

Multiply both sides by #"100 g"#.

#"32.7 g KCl"##=##"mass KCl"#

There are #"32.7 g KCl"# in #"100 g of solution"#.
