LESSON 1: Moles and Molar Mass. Objective: Calculate Molar Mass (gram formula mass) Fill in the table below. Calculate the GRAM formula mass (molar mass) and don’t forget the UNITS!!! CO2.
The mole is one of the most important concepts in chemistry, as it allows for quantitative calculation of amounts of substances that may take part in chemical reactions. Various formulas are used to calculate the amount of substance (in mol): = , where n = number of mol and M = molar mass (g mol–1) M. N.
