Answer to Question #219032 in General Chemistry for BreadKitty

Question

Ammonia is produced from its elements in a formation reaction. If 7.22 x 10²⁴ molecules of ammonia are produced, how many mole of ammonia was produced?

Answer 1

6.023×10²³ molecules of ammonia = 1 mole ammonia

7.81×10²⁴ molecules of ammonia = (1×7.81×10²⁴) / 6.023×10²³ 

                                                       = 12.96

12.96 moles of ammonia was produced.
