WebSolution Look for the atomic masses of hydrogen, sulfur and oxygen. H = 1.008 S = 32.06 O = 16 Therefore, the molecular mass of H2SO4 is 2 (1.008) + 32.06 + 4 (18) = 106.076 Hence, one mole of H2SO4 weights 106.076 grams. Since you need to find for 3.60 mol of H2SO4 = 3.60 mol x 106.076 g/mol = 381.87 g of H2SO4 Example 2. fisher price games appsWebatoms of (a) Cu = 63.55 g (c) S = 32.07 g (b) Hg = 200.59 g (d) He = 4.00 g.
