Lesson: Formula Mass Chemistry

Start Practising

In this lesson, we will learn how to define formula mass and calculate its value for given molecular formulas using atomic masses.

Lesson Plan

Students will be able to

recall the definition of atomic mass and the atomic mass unit,
recall how to identify the atomic mass from the periodic table,
define formula mass and its calculation from atomic masses,
state the different definitions of atomic mass, formula mass, and molecular mass,
use atomic masses to calculate the formula mass of a compound,
calculate formula masses from molecular and structural formulas.
