Molarity and solutions practice

Front

What does it mean to dilute a solution?

Back

To dilute a solution means to lower the concentration of solute per solvent.

Front

Which sweet tea would you expect to taste the sweetest? 1M, 3M, 3.1M, 2.5M

Back

3.1M

Front

The term molar, which describes a solution's concentration, is written as?

Back

M

Front

Calculate the molarity of the following solution: 1.0 mole of KCl in 750.0 mL of solution.

Back

1.3 M

Front

The ___ is the thing being dissolved.

Back

solute

Front

What is the definition of molarity?

Back

Molarity is 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 solvent in a solution?

Back

The solvent is the substance that dissolves the solute.

Front

If you have a 2M solution and dilute it to 1M, what happens to the concentration?

Back

The concentration decreases.

Front

What is the relationship between molarity and volume when diluting a solution?

Back

M1V1 = M2V2, where M is molarity and V is volume.
