Mass of CaCI2 (MM= 110.98 g/mol) formed in the reaction

Answer 1

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
