Ammonia is formed from the reaction of nitrogen and hydrogen according to the equation: N2(g) + 3H2(g) 2NH3(g)
What is the maximum number of moles of ammonia that can be formed from the reaction of 27 moles of hydrogen?
A
41
B
27
18
D
9

18 mol NH₃

General Formulas and Concepts:

Chemistry - Stoichiometry

Explanation:

Step 1: Define

RxN:   N₂ (g) + 3H₂ (g) → 2NH₃ (g)

Given:   27 moles H₂

Step 2: Stoichiometry

= 18 mol NH₃

Step 3: Check

We are given 2 sig figs.

Since our final answer is in 2 sig figs, we do not need to round.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
