Molarity

Front

What is molarity?

Back

Molarity (M) is a measure of concentration defined as the number of 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 the molarity of a solution made by dissolving 2 moles of NaCl in 1 L of water?

Back

2 M

Front

If you have 3 moles of solute in 0.5 L of solution, what is the molarity?

Back

6 M

Front

What is the formula to find the number of moles from molarity and volume?

Back

Moles = Molarity (M) × Volume (L).

Front

How many moles are in 2.5 L of a 4 M solution?

Back

10 moles.

Front

What is dilution in terms of molarity?

Back

Dilution is the process of reducing the concentration of a solute in a solution, typically by adding more solvent.

Front

What is the dilution formula?

Back

C1V1 = C2V2, where C is concentration and V is volume.

Front

If you dilute 50 mL of 6 M HCl to 200 mL, what is the new molarity?

Back

1.5 M.

Front

How do you prepare a 1 M solution from a concentrated solution?

Back

Use the dilution formula to calculate the required volume of concentrated solution.
