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.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
