How many moles of nitrous oxide (n2o) are produced when 1.40 moles of ammonium nitrate (nh4no3) decompes?

The answer to your question is 1.40 moles of N₂O

Explanation:

Balanced equation

                           NH₄NO₃   ⇒   N₂O  +  2 H₂O

                                 2     N   2

                                 4      H   4

                                 3      O   3

Process

1.- From the balanced equation, we know that 1 mol of NH₄NO₃ produces 1 mol of N₂O so, we use proportions to find the number of moles produced when 1.40 moles of NH₄NO₃ react.

                           1 mol of NH₄NO₃   1 mol of N₂O

                           1.40 moles               x

                           x = (1.40 x 1) / 1

                            x = 1.40 moles of N₂O are produced
