A pharmacist was tasked to prepare 7% glycerin solution by weight.The solution was found to have a density of 1.0149 g/cm3 at 20°C. Glycerin has a molecular weight of 92.0473 g/mol and density of 1.2609g/cm3 at 20°C. Question: 1. What is the weight in g of the solute? 2. What is the moles of solute? 3. What is the weight in kg of the solvent? 4. What is the molality of the solution? 5. What is the molarity of the solution? Show complete solution. Tnx.
