Question

During the experiment he obtained the following data:

Mass of Beaker = 48.936 g

Mass of Beaker & methyl salicylate = 50.139 g

Conc of NaOH sln = 4.0 M

Volume of NaOH added = 10.0 mL

Conc of HCl sln = 4.0 M

Volume of HCl added = 18.0 mL

Complete the following calculations based on this data:

Mass of methyl salicylate used = ______ g methyl salicylate

Moles of methyl salicylate used = ______ mol methyl salicylate

Moles NaOH used = _______ mol NaOH

Moles HCl used = ______ mol HCl

The first step of this reaction has the following balanced chemical equation:

C 8 H 8 O 3   ( l )   +   2   N a O H   ( a q ) → C 7 H 4 O 3 N a 2   ( s )   +   C H 3 O H   ( a q )   + H 2 O ( l )

Based on that reaction, the data, and your answers from above, answer the following questions:

1.1 How many moles of the intermediate product C 7 H 4 O 3 N a 2can be created based on the amount of methyl salicylate used?  mol C 7 H 4 O 3 N a 2

1.2 How many moles of intermediate product C 7 H 4 O 3 N a 2can be created based on the amount of NaOH used?  mol C 7 H 4 O 3 N a 2

1.3 Is methyl salicylate the LIMITING REAGENT for this reaction? (answer YES or NO)   

The second step of this reaction has the following balanced chemical equation:

C 7 H 4 O 3 N a 2   ( a q )   +   2   H C l   ( a q ) → C 7 H 6 O 3   ( s )   +   2   N a C l   ( a q )

Based on that reaction, the data, and your answers from above, answer the following questions:

2.1 How many moles of product can be produced based on the number of intermediate product used?  mol product

2.2 How many moles of product can be produced based on the number of moles of HCl use?  mol product

2.3 Is HCl the limiting reagent for this reaction? (Answer YES or NO)   

After the last step we determined the mass of the product obtained from the following data.

Mass of beaker = 51.246 g

Mass of beaker with product = 52.201 g

What is the Theoretical yield of this experiment? ___ g product

What is the Actual yield of this experiment? ____ g product

What is the Percent yield of this experiment? ____ %
