Answer 1

Solution :

Step I : No. of

molecules in 11.2 litres <br>

litres of

at N.T.P = 1 gram mol <br> 11.2 litres of

at N.T.P

gram mol <br> Now 1 gram mole of

contain molecules

<br>

gram mole of

contain molecules

<br> Step II. No. of carbon and oxygen atoms in

molecules of

<br> 1 molecule of

contains carbon atoms = 1 <br>

<br> Similarly, 1 molecule of

contains oxygen atoms = 2 <br>
