    A mole ratio is a conversion factor that relates the amounts in moles of any two substances in a chemical reaction. The numbers in a conversion factor come from the coefficients of the balanced chemical equation. The following six mole ratios can be written for the ammonia forming reaction above. Answer: look at the units, grams should cancel in the calculation, leaving an answer that has units of moles. This is illustrated below. • To convert volume to moles, first convert to mass using density, then convert to moles using molecular weight. Again, be sure to include all units in your calculations. It will help you to avoid errors ... whole-number ratios based on the number of moles of each element per 100 grams of compound. Calculate Step 2. Solve for the unknown. One hundred grams of compound has 5.9 g H and 94.1 g O. Multiply by conversion factors relating moles of the elements to grams: So, the mole ratio for 100 g of the compound is H 5.9 O 5.9. But formulas must have whole

Mole ratio practice worksheet

According to the balanced chemical equation, calculate the moles of reactants. CuSO 4 ⇒ 950.0 g / 159.607 g/mol = 5.95212 mol. Zn ⇒ 460.0 g / 65.38 g/mol = 7.03579 mol . So, CuSO 4 is limiting reagent. Grams of Cu: 5.95212 mol of Cu is produced (as 1 : 1 molar ratio involved) 5.95212 mol X 63.546 g/mol = 378.2 g. Percent yield : 295.8 g / 378.2 g = 78.21 %
