Question

Suppose the elements X and Y campaign to form two component x 2 and 3 y3 when 1 mole of xy to wait 10 gram and 0.05 more fx-322 vetan 9 gram the atomic weight of x and y are

Answer 1

Answer:

olar Mass -

The mass of one mole of a substance in grams is called its molar mass.

- wherein

 Molar mass of water = 18 g mol-1

Let the atomic weight of X  = x  

and atomic weight of  Y = y

then ,  x+2y = \frac{10}{0.1}

and  3x+2y = \frac{9}{0.05} = 180

as saluiy , we get  

x=40

y=30

Let the atomic weight of X  = x  

   and atomic weight of  Y = y

then ,  x+2y = \frac{10}{0.1}

and  3x+2y = \frac{9}{0.05} = 18

as saluiy , we get  

x=40
