A solution contains 50 g of common salt in 500 gm of water. Find the concentration of the solution in terms of percentage.
- A$500\%$
- B$50\%$
- Correct answerC$9\%$
- D$100\%$
Solution
Mass of solute (salt) = $50$ g
Mass of solvent (water) = $500$ g
Mass of solution = Mass of solute + Mass of solvent = $50 + 500 = 550$ g
Concentration of the solution = $\dfrac{\text{Mass of solute}}{\text{Mass of solution}} \times 100$
Concentration = $\dfrac{50}{550} \times 100 = \dfrac{100}{11} \approx 9.09\%$
The closest value among the given options is $9\%$.
Answer: $9\%$
Mass of solvent (water) = $500$ g
Mass of solution = Mass of solute + Mass of solvent = $50 + 500 = 550$ g
Concentration of the solution = $\dfrac{\text{Mass of solute}}{\text{Mass of solution}} \times 100$
Concentration = $\dfrac{50}{550} \times 100 = \dfrac{100}{11} \approx 9.09\%$
The closest value among the given options is $9\%$.
Answer: $9\%$
Hence, the correct answer is option: 'C'.
