Answer 1

Answer:

One mole of NH

3

contains = 6.022×10

23

molecules.

∴ 4 moles of NH

3

contains = 4×6.022×10

23

= 2.4088×10

24

molecules.

One mole of NH 3

contains = 6.022×10 power 23 molecules.

∴ 4 moles of NH 3

contains = 4×6.022×10 power 23

= 2.4088×10 power 24 molecules. ▁▁▁▁▁▁
