Question

based on the law of conservation of mass, what mass of product is formed during the reaction? oxygen gas + hydrogen gas → water 55.12 g? give your answer to the correct number of significant figures.

Explanation:

Step1: Apply Conservation of Mass

The total mass of reactants equals the mass of the product.

Step2: Identify reactant mass

The mass of the reactants (oxygen + hydrogen) is given as 55.12 g.

Step3: Match product mass

By the law, product mass = reactant mass.

Answer:

55.12 g
