Perform the following calculations. Make sure to use the correct number of significant figures. What volume (in milliliters) of acetophenone is needed to synthesize a sunscreen with 0.30 mL of cinnamaldehyde? What is the theoretical yield (in grams) of the sunscreen created from 0.30 mL of cinnamaldehyde and acetophenone? What volume (in milliters) of acetone is needed to synthesize a sunscreen with 0.30 mL of cinnamaldehyde? What is the theoretical yield (in grams) of the sunscreen created from 0.30 mL of cinnamaldehyde and acetone? What is the percent yield is 0.29 g of the sunscreen is collected from the reaction of 0.50 mL of cinnamaldehyde and acetone?
