Lesson: Molar Concentrations Chemistry • 10th Grade

In this lesson, we will learn how to calculate the molar concentration of a solution from the solvent volume and mass or moles of the dissolved solute.

Lesson Plan

Students will be able to

identify the formula ,
use the formula to calculate the concentration of a solution when given its volume and the number of moles,
convert from moles per dm³ to grams per dm³,
calculate the concentration when given the mass of a solid substance dissolved in a given volume,
recall the relationships between units of dm³, liter, cm³, and mL.
