WebApr 5, 2024 · 1. First, we need to know the solubility of KBr (potassium bromide) at 70ºC. The solubility of KBr at 70ºC is approximately 102 g/100 mL of water. Step 2/2 2. Now, we can calculate the amount of KBr that will dissolve in a given volume of water at 70ºC. For example, if we have 100 mL of water, then 102 grams of KBr will dissolve in it. WebSolution. The volume and molarity of the solution are specified, so the amount (mol) of solute is easily computed as demonstrated in Example 6.1.3: M = molsolute Lsolution. molsolute = M × Lsolution. molsolute = 5.30 molNaCl L × 0.250L = 1.325molNaCl. Finally, this molar amount is used to derive the mass of NaCl:
