Front

What is molarity?

Back

Molarity is a measure of concentration, defined as moles of solute per liter of solution.

Front

How do you calculate molarity?

Back

Molarity (M) = moles of solute / liters of solution.

Front

What is thermochemistry?

Back

The study of the heat energy associated with chemical reactions.

Front

What is the difference between endothermic and exothermic reactions?

Back

Endothermic reactions absorb heat, while exothermic reactions release heat.
