Review for T2Q2BT PARTII

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 the number of moles from molarity and volume?

Back

Number of moles = Molarity (M) × Volume (L).

Front

What is the dilution formula?

Back

The dilution formula is M1V1 = M2V2, where M1 and V1 are the molarity and volume of the concentrated solution, and M2 and V2 are the molarity and volume of the diluted solution.

Front

How many moles are in 0.045 L of 0.465 M potassium bromide?

Back

0.0209 mol.

Front

What volume of 10.0 M NaOH is needed to prepare 300.0 mL of 2.00 M NaOH?

Back

60.0 mL.

Front

How do you convert mL to L?

Back

To convert mL to L, divide the volume in mL by 1000.

Front

What is the relationship between moles, molarity, and volume?

Back

Moles = Molarity × Volume.

Front

If you have 6 mol of Sodium Hydroxide, how many liters would you need for a 1 M solution?

Back

6 L.

Front

What is the formula to find the volume of a solution needed for a specific molarity?

Back

Volume (L) = Moles / Molarity (M).

Front

How do you prepare a diluted solution from a concentrated solution?

Back

Use the dilution formula M1V1 = M2V2 to find the volume of the concentrated solution needed.
