- Example. In the titration of H 2 SO 4, sulfuric acid, the reaction requires 2 moles of NaOH per mole of H 2 SO 4.A complete titration of 50.00 mL of 0.100 molar H 2 SO 4 would therefore require 50.00 mL of 0.200 molar NaOH rather than the 25.00 mL needed for the monoprotic acid HCl in the preceding example.
- the same as the mass of one mole of the compound in grams. • Skill 3-1 Calculate the molecular mass of a compound as the sum of the atomic masses of its elements. • Molecular mass H 2 O = (2 x atomic mass of H) + atomic mass of O = 2(1.008 amu) + 16.00 amu = 18.02 amu • So, one mole of water (6.022 x 10 23 molecules) has a mass of 18.02 g.
- 2, moles H 2 = (1.7)(3)/2 = 2.6 moles b. 3 moles H 2SO 4 gives 1 mole product moles yield = 3 x 2.8 = 8.4 moles 3. Mole ratios: 2 mol Mg/ 2 mol MgO = 1 mol Mg: 1 mol product 1 mol O 2 / 2 mol MgO = 2 mol O 2 : 1 mol product 4. Mole ratios: 2 mol Al/ mol Al 2O 3, 1.5 mol O 2/ mol Al 2O 3. Hence, 5 mol Al and 3.75 mol O 2 are needed 5. Mole ...
