Consider the reaction

2 H2(g) + O2(g) → 2 H2O(l)

What is the mass of water, H2O(l), produced when 4.50 g of O2(g) reacts with excess H2(g)?

Express your answer with the appropriate units.

The coefficients in a balanced chemical equation represent the relative numbers of each molecule or formula unit and the relative number of moles of each molecule or formula unit. In a balanced equation, the stoichiometric relationships among the substances allow us to convert between quantities of reactants and products in a reaction.

Deuterium

Deuterium (written as D or 2H) is an isotope of hydrogen known as heavy hydrogen.
