Calculate the mass of oxygen per gram of nitrogen in each compound. 30.82 g n2 and 17.60 g o2

The mass of oxygen per gram of nitrogen in compound = 0.571

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
