if the mass of the products measured 120 g what would be the mass of the reactants

Step 1: Define the Problem

Identify the key components of the question that need to be addressed:

• The problem involves a chemical reaction.
• We need to find the mass of the reactants given the mass of the products.

Step 2: Break Down the Problem

Divide the problem into smaller, manageable parts:

• Understand the law of conservation of mass.
• Apply this law to find the mass of the reactants.

Step 3: Apply Relevant Concepts

Use appropriate academic theories or formulas to solve each part of the problem:

• According to the law of conservation of mass, the mass of the reactants is equal to the mass of the products in a closed system.

Step 4: Analysis, Verify and Summarize

Analyze each part in detail if necessary, carry out the calculations by steps:

• Since the mass of the products is given as 120 g, and assuming no mass is lost or gained in the reaction, the mass of the reactants must also be 120 g.

Final Answer

The mass of the reactants is 120 g.
