Find the percent by mass of sodium chloride in a 1.35M NaCl solution.the density of the solution is 1.05g/mL 相关知识点: 试题来源: 解析 1.35 mol/L的 NaCl溶液的质量分数是多少假设溶液体积是1000 mL,那么溶液质量 = 1000 ÷ 1.05 = 952.38 g溶质质量 = 1.35 × (23+35.5) = 78.975 g质量...
Divide the mass of the first dissolved component by the solution mass, and then multiply the result by 100 to calculate the mass percentage. In our example, the first dissolved compound is NaCl; the mass percent is: \(\frac{10 \text{g}}{136 \text{g}} \times 100\% = 7.35\%\) ...
