Hydrazine

{N}_2 {H}_4

(used as a fuel in rocket system) can be produced according to the following reaction.

{ClNH}_2+2 {NH}_3 \rightarrow {N}_2 {H}_4+{NH}_4 {Cl}

When

1.0 \mathrm{~kg} \, {ClNH}_2

is reacted with excess of

{NH}_3,

473 \mathrm{~g}

{N}_2 {H}_4

is produced. What is the percentage yield?

View answer and explanation

Correct option: A

76.12

Option A (76.12) is correct because the percentage yield is calculated by dividing the actual yield (473 g) by the theoretical yield (621.36 g) and multiplying by 100.
