NITROGEN form five compounds with oxygen in which 1.0g of nitrogen combines with 0.572, 1.14, 1.73, 2.28 and 2.85g of oxygen respectively. show that these figures agree with law of multiple proportion.

Five compounds with oxygen
i.e(NxOy)

Molar mass of nitrogen = 14 g/mol
Molar mass of oxygen = 16 g/mol

Case- I 

Nitrogen moles
= 1.0/14
= 0.07143

No.of moles of Oxygen
= 0.572/16
= 0.03575

Ratio N/O
= 0.07143/ 0.03575
= 1.998 
= 2.0

Thus chemical formula N2O.

Similarly,you can solve for the rest of the masses and will get

Molar N/O in th proportion
1)  1:1
2)  1:2
3)  2:3
4)  2:5.

These figures agree with law of multiple proportion as according to this the masses of one element with respect to the second combining element are always in the in the ratio of whole numbers.
