Question

A solution contains 35g of common salt in 300g of water. the concentration of the solution is

• A. 11.6%
• B. 88.3%
• C. 10.45%
• D. 89.5%

Answer 1

The correct option is A

11.6%

The explanation for the correct option:

(A) 11.6%

The formula used to calculate the percentage concentration of the solution is:

$$\begin{gathered} \%\mathrm{of}\mathrm{Concentration}\mathrm{of}\mathrm{solution}=\frac{\mathrm{Amount}\mathrm{of}\mathrm{solute}}{\mathrm{Amount}\mathrm{of}\mathrm{solvent}\mathrm{or}\mathrm{solution}}\mathrm{X}100 \\ =\frac{35}{300}\mathrm{X}100 \\ =11.6\% \end{gathered}$$

Thus option (A) 11.6% is the concentration of a solution containing 35g of common salt in 300g of water.
