Answer:
The atomic weight of the "y" compound is 80.
Explanation:
The carbon atomic weight = 12 g/mol
Atomic weight of "X" = [tex]2.96\times 2[/tex]
One mole of "X" element has mass 0.444 times the mass of one mole of element "Y".
So, atomic weight of "X" element =[tex]0.444\times Atomic\,weight\,of\,y[/tex]
[tex]Atomic\,weight\,of\,y= \frac{Weight\,of\,X}{0.444}[/tex]
[tex]= \frac{2.96\times 2}{0.444}= 80.7\equiv 80[/tex]
Therefore, The atomic weight of the "y" compound is 80.
