Please somebody help me with this problem!!! Ok here it is....

Na H CO3 + H C2 H3 O2 > C O2+ H2 0+ Na C2 H3 O2

There is 10.8 grams of baking soda and 16.4 grams of Vinegar.

A) Determine the limiting reactant using the salt product as the basis for your calculation

B) Once you've determined which one of the reactants is the limiting reactant determine the amount of Carbon Dioxide and water that will be produced.

C) Using the calculated data from A and B, determine how much of the excess reactant was really only needed for this reaction to be completed.

D) The Final product mass from the salt in an experimental yield was 6.4grams. Calculate the Percent error and the Percent Yield from this result.

Please i hope somebody can help me with this problem! Its due tommorow!

first find the molar masses for the different substances, then come back. I'll give you the next push
