Question

How many grams of ammonia (NH3) are produced from 6 moles of nitrogen?

Answer 1

204 grams

Explanations:

The chemical reaction formed from the reaction of Nitrogen and hydrogen is expressed as:

`3H_2+N_2\rightarrow2NH_3`

From the given reaction based on stochiometry, you can see that 1 mole of nitrogen produces 2 moles of ammonia.

Therefore, 6 moles of nitrogen will produce 12 moles of NH₃

Calculate the mass of ammonia produced

`\text{Mass}=nu\text{mber of moles }* molar\text{ mass}`

The molar mass of NH₃ = 14 + (1 * 3) = 17g/mol

`\begin{gathered} \text{Mass of ammonia = 12moles}*(17g)/(mol) \\ \text{Mass of ammonia = }204\text{grams} \end{gathered}`

Therefore, the mass of ammonia (NH3) produced from 6 moles of nitrogen is 204 grams.
