Question

How many atoms of carbon are present in 1.5mole of carbon ?

Answer 1

In one molecule of C O 2 there are 2 oxygen atoms. So, in 1 mole of C O 2 there has to be 2 X 6.022 X 10 23 atoms of oxygen. Hence, there will be one tenth of this number of oxygen atoms in 0.1 mole of carbon dioxide i.e. 1.2044 X 10 23 , and this is your answer.
