Molarity

IQ3: How are chemicals in solutions measured?

Students:

● manipulate variables and solve problems to calculate concentration, mass or volume using:

– 𝑐=𝑛𝑉 (molarity formula)

– dilutions (number of moles before dilution = number of moles of sample after dilution)

11. Molarity Concentration

This presentation introduces the concept of molarity.

This is the practical for calculating concentrations.
