What is the mass percentage of NaCl in the solution if 1.75g of NaCl is dissolved in 5.85g of water. |
23.02 29.9 23.98 25.00 |
23.02 |
The correct answer is Option (1) → 23.02 Mass percentage of a component of a solution is defined as: $\text{Mass percentage}=\frac{\text{Mass of the component in the solution}}{\text{Total mass of the solution}}× 100$ For mass percentage of NaCl in solution, it is given Mass of NaCl = 1.75g (Mass of component) Mass of water = 5.85g Total mass of the solution = 1.75 + 5.85 = 7.60 g Therefore, Mass percentage of NaCl = (1.75 ÷ 7.60) × 100 = 23.02% |
