Calculated the Relative Molecular Mass of calcium (II) chloride using the periodic table.
Calcium (II) has a charge of 2+ and each chloride has a -1 charge giving a formula of CaCl2 when balancing the charges out. Ca (Relative Atomic Mass) = 40.08 and Cl (Relative Atomic Mass) = 35.45So Relative Molecular Mass of CaCl2 is 40.08 + 35.45*2 = 110.98
