What is the definition of solvent?

Back

The solvent is the substance that dissolves the solute, typically a liquid.

Front

What is the formula for calculating molarity?

Back

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

Front

What is the relationship between molarity and concentration?

Back

Molarity is a measure of concentration, specifically the number of moles of solute per liter of solution.

Front

If you dilute a solution, what happens to its molarity?

Back

The molarity decreases when a solution is diluted.
