Question

Determine how many moles of hydrogen are needed to produce 50 grams of ammonia.

Answer 1

Answer:

4.41 moles of hydrogen

Explanation:

N2 + 3H2 => 2NH3

No of mole = mass/molar mass

No of mole = 50/17 = 2.94

3 moles of H2 gives 2 moles of ammonia

X moles of H2 gives 2.94 moles of ammonia

X mole of H2 = 3 moles of H2 * 2.94 moles of ammonia/ 2 moles of H2

X = 4.41 moles of hydrogen
