由于称取了纯 NaCl 加入水中溶解，因此溶液中的 NaCl 的摩尔数为：moles of NaCl = mass of NaCl / molar mass of NaCl = 0.1169 g / 58.44 g/mol = 0.002001 mol 3.根据反应方程计算 AgNO3 的摩尔数：根据反应方程，1 mol 的 NaCl 可以与 1 mol 的 AgNO3 反应生成 1 mol 的 AgCl...
To solve the problem of determining the mass of NaCl that must be dissolved in 65 g of water to lower the freezing point by 7.5°C, we can follow these steps:Step 1: Understand the Freezing Point Depression Formula The formula
A mass of 0.630 g of NaCl is dissolved in 525 g of water. Calculate the molality. mass of NaCl = 0.630 g mass of H2O = 525 g molar mass of NaCl = 58.44 A solution is prepared by dissolving 6.4 grams of HCl in 64....
