The molar mass of calcium chloride (cacl2) is 110.98 g/mol. if you were to calculate the number of moles in 23.4 g of cacl2, which example shows the correct way to set up the calculation

The example which show the correct way to set up the calculation of moles of CaCl2 is calculated as follows

moles of CaCl2 = mass of CaCl2(23.4 g/molar mass of CaCl2 ( 110.98 g/mol)

moles of CaCl2 = 23.4 g/ 110.98 g/mol = 0.211 moles
grams will cancel out each other

The number of moles of 23.4g of calcium chloride with a molar mass of 110.98g/mol is calculated to be 0.211mol.

HOW TO CALCULATE NUMBER OF MOLES:

The number of moles of a substance can be calculated by dividing the mass of the substance by its molar mass.

According to this question, calcium chloride has a molar mass of 110.98g/mol and a mass of 23.4g. The number of moles is calculated as follows:

no. of moles of CaCl2 = 23.4g ÷ 110.98g/mol

no. of moles = 0.211mol

Therefore, the number of moles of 23.4g of calcium chloride with a molar mass of 110.98g/mol is calculated to be 0.211mol.
