Finally, the PDF touches on "real world" chemistry: calculating percentage yield (actual/theoretical) and atom economy, which is crucial for green chemistry principles.

Concentration of a solution is often expressed in molarity (M), which is moles of solute per liter of solution.

Example: What is the molarity of a solution made by dissolving 2 moles of NaCl in 500 mL of water? Jim Clark Chemistry Calculations.pdf

First, convert mL to liters: 500 mL = 0.5 liters.

[ M = \frac\textmoles of solute\textliters of solution = \frac20.5 = 4 M ] Finally, the PDF touches on "real world" chemistry:
