Question

or the reaction: 2X 3Y r 3Z, the combination of 2.00 moles of X with 2.00 moles of Y produces 1.75 moles of Z. What is the percent yield of this reaction

Answer 1

Answer:

% yield = 58.33 %

Explanation:

• 2X + 3Y → 3Z

∴ moles X = 2.00 mol

∴ moles Y = 2.00 mol

∴ moles Z = 1.75 mol = moles produced

• % Yield = ( moles produced / theoretical moles ) × 100

theoretical moles:

⇒ moles Z = (2.00 mol X)*(3 mol Z/2 mol X) = 3.00 mol Z

⇒ % yield = [(1.75 mol produced)/(3.00 theoretical mol)]×100

⇒ % yield = 58.33 %
