Question

Mass percentage of a solution containing 10 g of solute in 100 g of water is 10%.

• A. True
• B. False

Answer 1

The correct option is B

False

Mass percentage of a solution is given as : $\frac{Massofsolute}{Massofsolution}$

Here, mass of solution = mass of solute + mass of solvent

= 10g + 100g = 110g

So, mass percentage = $\frac{10}{110}\times 100$ = 9.09 %.
