Answer to Question #140295 in General Chemistry for George

Question

Ammonia is produced from its elements in a formation reaction. If 7.19 x 10²⁴ molecules of ammonia are produced, how many mole of ammonia was produced?

Answer 1

Given,

Number of molicule of amomonia produce = 7.19 x 10²⁴ molecules

We know,

6.023 x 10²³ molicule = 1 mole

1 molicule = (1/(6.023x10²³)) mole

7.19 x 10²⁴ molecules = (7.19x10²⁴/ (6.023 x 10²³))

= 11.937 mole

Hence, 11.937 mole of ammonia produced
