Answer:-
Given:-
Mass of solute = 36 g (NaCl)
Mass of solvent = 100 g (Water)
_________...
∴ Mass of solution :-
= Mass of solvent + Mass of Solute
= 36 g + 100 g
= 136 g
We know,
Mass by mass percentage of solution:- (To find concentration)
(Mass of solute/Mass of solvent) × 100℅
∴ Concentration :-
(36 g)/(136 g) × 100℅
= 36/136 × 100℅
= 0.264 × 100%
= 26.4 % (Answer)
