Understanding Solutions and Concentrations Review

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 molarity of a solution?

Back

Molarity = moles of solute / liters of solution.

Front

What is the formula for dilution?

Back

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

Front

What is the definition of percent by volume?

Back

Percent by volume is the volume of solute divided by the total volume of solution, multiplied by 100.

Front

How do you calculate percent by volume?

Back

Percent by volume = (volume of solute / total volume of solution) x 100.

Front

What is molality?

Back

Molality (m) is a measure of concentration defined as the number of moles of solute per kilogram of solvent.

Front

How do you calculate molality?

Back

Molality = moles of solute / kilograms of solvent.

Front

What is the relationship between molarity and molality?

Back

Molarity is based on the volume of the solution, while molality is based on the mass of the solvent.

Front

If you dilute a solution, what happens to its molarity?

Back

The molarity decreases as the volume of the solution increases.

Front

What is the new molarity after diluting a 6 M solution to 3 liters?

Back

2 M.
