1.) Write down the number of atoms that comprise each compound on either side of the equation. Using the chemical equation you can identify the atoms of each element in the reaction. Because a chemical reaction can never create or destroy new matter, a given equation is unbalanced if the number (and types) of atoms on each side of the equation don't perfectly match.Don’t forget to multiply through by a coefficient or subscript if one is present.

For example, H2SO4 + Fe ---> Fe2(SO4)3 + H2On the reactant (left) side of the equation there are 2 H, 1 S, 4 O, and 1 Fe.On the product (right) side of the equation there are 2H, 3 S, 12 O, and 2 Fe.

=0.147 mol H2O

0.147 mol (H2O) / 1 mol (h2o) x 18.015 g (h2o)

=2.65 g H2O
