Q29 / 160 · AP EAMCET 2020 (23 Sep Shift 1) · Chemistry

Calculate the mass percentage of $3 g$ of solute $A$ dissolved in $18 g$ of water.

A
$15.28 %$
Correct answer
B
$14.28 %$
C
$16.28 %$
D
$17.28 %$

Solution

Mass percent of solute $= \frac{Mass of solute}{Mass of solution} \times 100$

$= \frac{3}{21} \times 100 = 14.28$

Hence, the correct answer is option: 'B'.
