Front

What is molarity?

Back

Molarity is a measure of the concentration of a solute in a solution, expressed as moles of solute per liter of solution (mol/L).

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 adding 1.565 moles of PbNO3 to 500 mL?

Back

3.13 M

Front

How do you convert grams of a solute to moles?

Back

Moles = grams / molar mass of the solute.

Front

What is the molarity of a solution which contains 22.40 grams of NaCl in 500.0 mL of solution?

Back

0.77 M

Front

How do you find the volume of a solution needed for a specific molarity?

Back

Volume (L) = moles of solute / molarity.

Front

How many Liters are required to make 3.5 M hydrochloric acid (HCl) using 1.1 moles?

Back

0.31 L

Front

In a solution, what is the solvent?

Back

The solvent is the substance that dissolves the solute; in seawater, the solvent is water.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture in which the components are not uniformly distributed, such as oil and water.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture in which the components are uniformly distributed, such as salt water.
