Answer 1

Question #136850

How many molecules (not moles) of NH 3 are produced from 5.29 * 10 ^ - 4 g of H 2 ?

Answer

N₂+3H₂ →2NH₃

Mol of H2 used= 5.29×10^-4÷2

                           = 0.0002645 mol

Mol of NH₃ produced = 0.0002645 mol× 2/3

                                      = 0.000176333

1 mol of NH₃ → 6.022×10²³ molecules

0.000176333 mol →? molecules

 = 0.000176333× 6.022×10²³ molecules

 = 1.061879333×10²⁰ molecules

 = 1.06×10²⁰ molecules
