Question

what volume is occupied at NTP by
1) 1.4 gram of nitrogen
2) 0.2 gram of ammonia ​

Answer 1

Answer:

1)

Explanation:

1.4 gram of nitrogen

Answer 2

Answer:

1. number of moles of nitrogen = gn mass/ molecular mass

                                                    = 1.4/ 14

                                                    = 0.1 mol

            1mol nitrogen occupy 22.4 L

          hence 0.1 mol of nitrogen occupies 2.24 L

2. number of moles of ammonia = 0.2/17

                                                      = 0.0117 mol

          1 mol of ammonia occupies 22.4 L

        hence 0.0117 mol occupies 0.262L
