Moles, Molar Mass, Mass Calculations

Published on 10/20/2009

Activity Overview

The molar masses of the most common elements have been defined in the TI-Nspire file. Using moles = mass/(molar mass) and the rearrangement of this formula, calculations are easy to perform in year 11/12 chemistry. For example, given 120g of NaCl, input 120/(Na+Cl) and the moles is calculated for you.

Before the Activity

Ensure that students have been introduced to the mole calculation concept.
