Question

What mass of NH3 can be made from 1221g of H2? Write in your answer rounded to the nearest whole number.

Answer 1

Answer:

6919g

Explanation:

N2+3H2->2NH3

3H2=6g and2NH3=34g

6g oh H2 gives 34g of NH3

so 12w1g will give 34×1221/6 g of NH3

using unitary method

Answer 2

Given :

Mass of H₂ = 1221 g

To find :

The mass of NH₃ that can be produced

Solution :

• From the following reaction     N₂+3H₂⇔2NH₃

• Mass of 3H₂ = 6g

• Mass of 2NH₃ = 34g

• From the reaction 6g of H₂ produces 34 g of NH₃

• 1221 g of H₂ produces = (34×1221) /6 g of NH₃

• Mass of NH₃ = (34×1221) /6

                     =6919 g

Mass of NH₃ that can be produced is 6919g
