How to Calculate the Number of Moles in a Sample of Calcium Nitrate

Question:

What is the process to determine the number of moles in a given sample of calcium nitrate?

Answer:

To find the number of moles in a sample of calcium nitrate, you need to follow a specific calculation method.

Calcium nitrate, with the chemical formula Ca(NO3)2, is a compound that consists of calcium and nitrate ions. In order to calculate the number of moles in a sample of calcium nitrate, you will need to know the molar mass of the compound and the mass of the sample.

The molar mass of Ca(NO3)2 can be determined by adding together the atomic masses of calcium, nitrogen, and oxygen in the compound. The molar mass of Ca(NO3)2 is 164.10 grams per mole (g/mol).

To calculate the number of moles in a sample of calcium nitrate, divide the mass of the sample by the molar mass of Ca(NO3)2. For example, if you have a 55.27-gram sample of calcium nitrate, the calculation would be as follows:

Moles = Mass of sample (in grams) / Molar mass of Ca(NO3)2

Moles = 55.27 g / 164.10 g/mol

Moles = 0.3368 moles

Therefore, the sample of calcium nitrate would contain 0.3368 moles.
