## Weight percentage=[Weight of solute+ weight of solventWeight of solute​]×100

Let the weight of the solute be 'x'.
2.38=x+500x×1002.38x+1190=100x1190=97.62xx=97.621190=12.190g
Mass of solute =12.19 grams

Weight percentage=[
Weight of solute+ weight of solvent
Weight of solute
]×100
Let the weight of the solute be 'x'.
2.38=
x+500
x×100

⟹2.38x+1190=100x
⟹1190=97.62x
⟹x=
97.62
1190
=12.190g
∴ Mass of solute =12.19 grams
