Question

You start with two reactants. One reactant has a mass of 13.6 grams and the other reactant has a mass of 72.9 grams. 22 grams of gas are released during the reaction. What is the total mass of all of the products formed in this reaction?

Answer 1

64.5g

Step-by-step explanation:

First you add the mass of reactant 1 and reactant 2, then you simply subtract the amount of gas released from your answer, and that would be the total mass of ALL the products formed.

My work:

13.6g + 72.9 = 86.5g

86.5g - 22g = 64.5g
