Current Question (ID: 18046)

Question:

$\text{If 22 g of benzene is dissolved in 122 g of CCl}_4, \text{ the mass percentage of CCl}_4$ $\text{and benzene respectively are-}$

Options:

1. $15.28\ \%, 84.72\ \%$
2. $84.72\ \%, 15.28\ \%$
3. $8.72\ \%, 91.28\ \%$
4. $91.28\ \%, 8.72\ \%$

Solution:

$\text{Mass percentage can be defined as the ratio of Mass of the}$ $\text{component of the solution and total mass of the solution multiplied by}$ $100\%. \text{Explanation:}$ $\text{Step 1:}$ $\text{Mass percentage of Benzene} = \frac{\text{Mass of benzene}}{\text{Total mass of the solution}} \times 100$ $\Rightarrow \frac{22}{22+122} \times 100 = 15.28\ \%$ $\text{Step 2:}$ $\text{Mass percentage of CCl}_4 = \frac{\text{Mass of CCl}_4}{\text{Total mass of the solution}} \times 100$ $\Rightarrow \frac{122}{22+122} \times 100 = 84.72\ \%$
