Below is the reaction you will be performing today:

To perform the synthesis you will be using the following reagents:

p-aminobenzoic acid (PABA)	ethanol
MR = 137.14 g/mol	MR = 47.07 g/mol
0.80 g	10 mL (density: 0.789 g/mL)

Calculate (to 2 significant figures):

No. of moles of PABA: Answer = _____ mol

Mass of ethanol: Answer = _____ grams

No. of moles of ethanol: Answer = _____ mol

Determine the molar ratio of PABA : ethanol being used today (round to the nearest integer):

PABA	:	ethanol
Ratio = nPABA / nPABA		Ratio = nethanol / nPABA
Ratio = 1	:	Answer = ______

Out of PABA and ethanol, which reagent will be used in excess?

a) PABA

b) Ethanol

c) Neither is in excess – they will be used in their stoichiometric ratios
