The volume of necessary hydrogen gas for the given conditions equals to
equals
.
Explanation
## Step1: Recognize the type of problem. This problem is a stoichiometry problem in the field of chemistry. It is about determining the balanced equation for a given chemical reaction and calculating the volume of reactant gas when a certain volume of different gas is given. ## Step2: Understand the given balanced equation. The balanced chemical equation is given as: \( \mathrm{N}_{2}(g)+3 \mathrm{H}_{2}(g) \rightarrow 2 \mathrm{NH}_{3}(g) \).From this we understand that one volume of nitrogen gas reacts with three volumes of hydrogen gas to produce two volumes of ammonia gas. ## Step3: Calculate necessary volume. We are asked to find the volume of hydrogen gas that can react with
of nitrogen gas, at the same temperature and pressure. According to the balanced reaction, one volume of nitrogen gas (N_{2}) reacts with three volumes of hydrogen gas (H_{2}). Therefore, to determine the volume of hydrogen gas, we multiply the volume of nitrogen gas by the ratio of the volumes of nitrogen to hydrogen in the reaction, which is 1:3.
