Molarity and solutions practice

Front

What is the formula for calculating molarity?

Back

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

Front

In a solution of Kool-Aid, which component is the solvent?

Back

Water is the solvent.

Front

How can you decrease the concentration of a solution?

Back

By adding more solvent.

Front

What is a saturated solution?

Back

A saturated solution is one in which the solvent cannot dissolve any more solute at a given temperature.

Front

What is a solvent?

Back

A solvent is the substance that dissolves the solute in a solution.

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved, while a solvent is the substance that does the dissolving.

Front

What happens to the molarity of a solution if you dilute it?

Back

The molarity decreases when you dilute a solution.

Front

What is the unit of molarity?

Back

The unit of molarity is moles per liter (mol/L).

Front

What is the relationship between moles of solute and volume of solution in molarity?

Back

Molarity is directly proportional to the number of moles of solute and inversely proportional to the volume of solution.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature.
