A student created a chemical reaction as part of a science experiment in which 4.0 grams of one reactant combined completely with 12.5 grams of a second reactant to form a product. What is the mass, in grams, of the product formed by this chemical reaction in a closed system?

Question

A.
8.5
B.
12.9
C.
16.5
D.
52.5

Answer 1

To calculate the mass of the product formed by this chemical reaction, we need to first determine the total mass of the reactants.

Total mass of reactants = mass of reactant 1 + mass of reactant 2
Total mass of reactants = 4.0 grams + 12.5 grams
Total mass of reactants = 16.5 grams

Since the reaction takes place in a closed system, the total mass of the reactants must be equal to the total mass of the products.

Therefore, the mass of the product formed by this chemical reaction is 16.5 grams.

So, the correct answer is:

C. 16.5
