FA 3.4 Worksheet on Solutions Stoichimetry Read the following items with great comprehension. Give what is asked. Show your complete solutions and box your final answer with proper units and the number of significant figures. Attach your solutions and answers in pdf or jpeg file. 1. In drilling oil wells, aqueous solutions of calcium bromide with proper concentrations. Find the molality and molarity of a 52.1% CaBr₂ by mass solution. (Density = 1.70 g/mL) 2. Find the mass, in grams, of magnesium hydroxide that will be produced when 25.0 mL of 0.235-M magnesium nitrate was combined to 30.0 mL of 0.260-M potassium hydroxide. See chemical equation: Mg(NO3)2(aq) + KOH → KNO3(aq) + Mg(OH)2(s) 3. If 35.0 mL of 0.128 M calcium bromide was used, calculate the volume, in liters, of 0.415 M silver nitrate needed to produce a solid product of silver bromide.
