Explanation:
%m/m = mass of solute / mass of solution x 100
mass of solute = 5 g
mass of solution = 250+5=255g
%m/m= 5/255x100
%m/m= 1.9

Answer :
mass of solute ( glucose) = 5g
mass of solvent ( water ) = 250 g
mass of solution = mass of solute + mass of solvent
= ( 5 + 250 )g
= 255 g
concentration of solution = mass of solute / mass of solution ×100
= 5/255 ×100
= 1.96 %
