Question

What is the mass percentage of carbon tetrachloride if 22 g of benzene is dissolved in 122 g of carbon tetrachloride? (A) 84.72 % (B) 15.28 % (C) 50 % (D) 44 %

Tardigrade Admin · Accepted Answer

Mass of solution = Mass of C6H6 + Mass of CCl4 = 22 + 122 = 144 g Mass % of CCl4 = (122/144) × 100 = 84.72 %

Q. What is the mass percentage of carbon tetrachloride if $22 g$ of benzene is dissolved in $122 g$ of carbon tetrachloride?

$84.72%$

$15.28%$

$50%$

$44%$

Mass of solution = Mass of $C_{6} H_{6} +$ Mass of $CC l_{4}$
$= 22 + 122 = 144 g$
Mass $%$ of $CC l_{4} =$ $\frac{122}{144} \times 100 = 84.72%$
