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
