An element forms two oxides containing, 50% & 40% of oxygen respectively by weight of the element. Does these oxides illustrate the law of multiple proportions :-

Answer»

Yes
No
NOTHING can be said
Any one of the above

Solution :40 g of element `to` 60g of oxygen , 1g `to` 60/40=1.5 g
50 g of element `to` 50 g of oxygen , 1 g `to` 50/50=1g
THEREFORE the weight of oxygenthat combine with 1 g of the element in the two oxides are in the ratioof 1:1.5 or 2:3 which is a SIMPLER ratio . Hence it holds the law of multiple proportions
