Question
CBSEENCH11005008

The following data were obtained when dinitrogen and dioxygen react together to form different compounds:

Mass of dinitrogen               Mass of dioxygen
(i) 14g                                              16g
(ii) 14g                                             32g
(iii) 28g                                            32g
(iv) 28g                                            80g

which law of chemical combination is obeyed by the above experimental data? Give its statement?

Solution
By fixing the mass of dinitrogen as 28g, we can calculate the masses of dioxygen that will combine with 28g of dinitrogn.   
  1 st space compound comma space space space space Mass space of space dioxygen space space equals space 16 over 14 cross times 28 space equals space 32 straight g
2 nd space compound comma space space space Mass space of space dioxygen space space equals space 32 over 14 cross times 28 space equals space 64 space straight g
3 rd space compound space space space space space Mass space of space dioxygen space equals space 32 over 28 cross times 28 space equals space 32 straight g
4 th space compound. space space space Mass space of space dioxygen space space equals 80 over 28 cross times 28 space equals space 80 straight g

These are in the ratio of 32 : 64 : 32 : 80 i.e. 1:2:1:5 which is simple whole number ratio. Hence the given data obeys the law of multiple proportions. For definition refer to the answer of question 40.
