This video will demonstrate to the nursing student how to calculate molarity. Molarity is the relationship between the moles of a solute and the liters of a solution. Calculating molarity is as simple as dividing the moles of a solute by the liters of solution.

The molarity formula is Molarity = grams or solute / liters of solution. The real complication for this type of problem is calculating moles of solute. However, you should not let that intimidate you. The moles of solute can be easily calculated by simply dividing the grams of solute by the molar mass of the solute. Of course, molarity problems can be further complicated by forcing the student to also calculate the molar mass of the solute from the molecular formula. Do not get discouraged! Molar mass can be easily calculated by adding up the molar masses of each element in the formula.

For more on calculating molar mass please see the following video:

Molarity is an important concentration unit used in chemistry. The better you understand molarity the easier a lot of other chemistry problems will be for you!
