Question

0.6 carbon was burnt in air to form carbon dioxide the no of molecule of carbon dioxide introduced in air will be how much

Answer 1

To find the molecules, you first need the moles, then Avogadro Number. 

0.6g C (1 mole/12.0096g) (6.022 x 10^23 molecules/moles) 
= 0.30 x 10^23 molecules 

= 3.0 x 10^22 molecules
