Answer» Mass (solute) = 40 gram Mass (solvent) = 320 gram Mass (solution) = Mass (solute) + Mass (solvent) = 40 gram + 320 gram = 360 gram ∴ Mass % (solution) = [ Mass (solute)/Mass (solvent)]× 100 = [40/360]× 100 = 11.1 %

Answer»

Mass (solute) = 40 gram

Mass (solvent) = 320 gram

Mass (solution) = Mass (solute) + Mass (solvent)

= 40 gram + 320 gram

= 360 gram

∴ Mass % (solution) = [ Mass (solute)/Mass (solvent)]× 100

= [40/360]× 100

= 11.1 %
