Question

x and y are two different elements having their atomic masses in 2 :4 ratio the compound formed by the combination of x and y are contains 50%x by weight empirical formula is​

Answer 1

Answer:

Let the atomic weight of X be w and atomic weight of Y is 2w.

Let the empirical formula be X

m

Y.

So, 0.5=

m×w+2w

m×w

On solving we get, m=2.
