The mass of oxygen per gram of nitrogen in compound = 0.571
<h3>Further explanation
</h3>
Dalton's law of multiple comparisons states that if elements are forming two or more kinds of compounds, if the mass of one of the elements is known to be the same / fixed, then the mass of the second element in the two compounds will have a ratio as a simple integer.
o according to Dalton if for example there are elements X and Y form two compounds, for example XY and X₂Y₃. and the mass of element X is made constant then
XY changed X₂Y₂
X₂Y₃ is still X₂Y₃
So the ratio of element Y in compounds 1 and 2 is 2: 3 which shows a simple ratio
Nitrogen itself can react with oxygen to form four different compounds.
The compound have 30.82 g N₂ and 17.60 g O₂
So the mass of oxygen per gram of nitrogen in compound.
= 17.60 g : 30.82 g = 0.571
