Front

What is the molarity of a solution made by diluting 26.5 mL of 6.00M HNO₃ to a volume of 250 mL?

Back

0.636 M

Front

What happens during a dilution?

Back

Water is added to the volume of solution.

Front

Define molarity (M).

Back

Molarity is the number of moles of solute per liter of solution.

Front

What is the relationship between volume and concentration in a dilution?

Back

As the volume increases, the concentration decreases.

Front

If you have 200 mL of a 0.5 M solution and dilute it to 800 mL, what is the new concentration?

Back

0.125 M

Front

What does it mean to dilute a solution?

Back

To dilute a solution means to decrease its concentration by adding more solvent.

Front

How do you calculate the number of moles in a solution?

Back

Moles = Molarity × Volume (in liters).
