Chemistry: Molarity and Dilution

Front

A solution that has water as the solvent is called a(n).....

Back

Aqueous Solution

Front

How do we make a dilution?

Back

Add more solvent

Front

As we dilute a solution.....

Back

The volume increases and the molarity (M) decreases

Front

What is the formula for calculating molarity?

Back

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

Front

What is the molarity of a solution containing 400 g of CuSO4 (FM: 159.6 g/mol) in 4.0 L of solution?

Back

0.626 M

Front

What does 'dilution' mean in chemistry?

Back

Dilution is the process of reducing the concentration of a solute in a solution.

Front

What is the relationship between volume and molarity during dilution?

Back

As volume increases, molarity decreases.

Front

If you have a 2 M solution and dilute it to 4 L, what will be the new molarity if you add 2 L of solvent?

Back

1.5 M

Front

What is the definition of solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

What is the definition of solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution.
