Assuming a one to one stoichiometry, starting with 8.93 mL of 2-methylpropan-2-ol, how many grams of 2-chloro-2-methylpropane should be produced? This is called the theoretical yield. Round to three significant figures. Assuming the molecular weight of 2-chloro-2-methylpropane is 92.5, and the molecular weight of 2-methylpropan-2-ol is 74.

Homework Answers

Answer #1

density of 2-methylpropan-2-ol = 0.781

Density = mass/volume

mass of 2-methylpropan-2-ol = density x volume = 0.781 x 8.93 = 6.974 grams

1 mole of 2-methylpropan-2-ol will produce 1 mole of 2-chloro-2-methylpropane

no. of moles of 2-methylpropan-2-ol = 6.974 / 74 = 0.09425 moles

0.09425 moles of 2-methylpropan-2-ol will produce 2-chloro-2-methylpropane = 0.09425 moles

Weight of (theoretical yield) 2-chloro-2-methylpropane formed = 0.09425 x 92.5 = 8.718 grams

Report how much glucose was present before we started fermentation (this is 800 mg/dL for everybody because we just did one representative test). Use this number to calculate the maximum theoretical mass (in grams) of ethanol that we could have produced in the fermentation. In other words, given that one molecule of glucose produces two molecules of ethanol, calculate how many grams of ethanol could be produced if every single glucose molecule was converted into two ethanol molecules (this is...
