Question

Be sure to answer all parts. Ammonia is a principal nitrogen fertilizer. It is prepared by the reaction between hydrogen and nitrogen. 3H2(g) + N2(g) → 2NH3(g) In a particular reaction, 4.00 moles of NH3 were produced. How many moles of H2 and how many moles of N2 were reacted to produce this amount of NH3?

Answer 1

moles of H2

Mole ratio of H2 to NH3 is 3: 2

if 3: 2

? 4

= 4*3/2= 6

6moles of H2

moles of N2

mole ratio of N2 to NH3 is 1: 2

if 1 : 2

? 4

4*1/2 = 2

2 moles of N2
