Summary:
- The molarity (M) of a solution is the number of moles of solute dissolved in one liter of solution.
- Percentage measurements are based on either mass or volume.
- Molarity equation can be rearranged to solve for moles, which can then be converted to grams.Calculations using the concept of molarities are described.
- See sample problem 16.3.3 for the solution to the problem.
- The solution is prepared by dissolving 42.23 g of NH4Cl into enough water to make 500.0 mL of solution, which has a molarhip of 1.579 M.
