Question

In a chemical reaction, a reactant X reacts with 5.8g of reactant Y producing 9.6g of product Z. Find out the amount of reactant X if both reactant X and Y were fully consumed during the reaction. State the law used.

Answer 1

Given:

Y reactant weight = 5.8g

Z reactant weight = 9.6g

Therefore,

X reactant weight = 3.8g

Therefore, law used is;

The Law of Conservation of Mass.
