How much heat gets released or absorbed in a chemical reaction? We'll learn how to calculate this. We will use molar mass and conversion factors to figure out the enthalpy change in exothermic and endothermic reactions, which are represented by thermochemical equations.

Whats the Difference Between Molarity and Molality?

$Converting Between Grams and Moles Well learn how to convert back and forth between grams and moles. For each example, well do it two ways. First, a thinking through it approach, that shows how you multiply moles by the molar mass to convert from moles to grams, and how you divide grams by the molar mass to convert from grams to moles. Second, well use a conversion factor method where we write units based on molar mass information, and set up fractions to correctly cancel the units.
