CuClO₃

<u>Step 2: Find MM</u>

Molar Mass of Cu - 63.55 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of CuClO₃ - 63.55 + 35.45 + 3(16.00) = 147.05 g/mol

denis-greek [22]

Answer:

The answer to your question is the letter D. 12

Explanation:

Unbalanced chemical reaction

               Al(OH)₃  +  H₂SO₄  ⇒   Al₂(SO₄)₃  +  H₂O

           Reactants              Elements         Products

                  1                            Al                      2

                  1                            S                       3

                  5                            H                      2

                  7                            O                      13

Balanced chemical reaction

              2Al(OH)₃  +  3H₂SO₄  ⇒   Al₂(SO₄)₃  +  6H₂O

           Reactants              Elements         Products

                  2                            Al                      2

                  3                            S                       3

                 12                            H                     12

                 18                            O                     18

Sum up the coefficients

Result = 2 + 3 + 1 + 6

          = 12
