Question
If $1 \mathrm{g}$ of hydrogen combines completely with $8 \mathrm{g}$ of oxygen to form water, how many grams of hydrogen are needed to combine completely with $24 \mathrm{g}$ of oxygen?
Step 1
This is given by the equation: $$1 \mathrm{g} \, \mathrm{H}_2 + 8 \mathrm{g} \, \mathrm{O}_2 \rightarrow \mathrm{H}_2\mathrm{O}$$ Show more…

Introduction
A mixture of $0.0375 \mathrm{~g}$ of hydrogen and $0.0185 \mathrm{~mol}$ of oxygen in a closed container is sparked to initiate a reaction. How many grams of water can form? Which reactant is in excess, and how many grams of it remain after the reaction?
