Stoichiometry And Stoichiometric Calculations

Step 1: Use the molarity equation to calculate moles of ethylacetate.
The molarity equation is: The moles of ethylacetate is: Step 2: Use the stoichiometric relationship.
Since the reaction goes to 100% conversion and the stoichiometry is 1:1, the moles of MeMgBr required will be equal to the moles of ethylacetate. Thus, the moles of MeMgBr required is also .
Step 3: Calculate the volume of MeMgBr solution.
The molarity of MeMgBr is 0.2 M, so the volume required is: Thus, the volume of MeMgBr required is 1.3 mL.
