The following data are obtained when dinitrogen and dioxygen react to gether to form different compounds:
`{:(,,"Mass of dinitrogen",,"Mass of dioxygen"),(i.,,14 g,,16 g),(ii.,,14 g,,32 g),(iii.,,28 g,,32 g),(iv.,,28 g,,80 g):}`
a. Which law of chemical combination is obeyed by the above experimental data? Give its statement.
d. Fill in the blanks in the following conversions:
I. `1 km`= ....... mm= ......pm
II. `1 mg=` ........ `kg=` ......... ng
III. `1 mL`= ........ L= ......... `dm^(3)`

Answer

(a) Low of,multi proportin
(b) (i) ans:`(10^(6) mm,10^(15) pm)`
(ii) Ans :`(10^(-6) kg , 10^(6), ng)`
`(iii) Ans : (10^(-3) L ,10^(-3)dm ^(3))`
