Question

A compound contains two elements ' $X$ ' and ' $Y$ ' in the ratio of $50 \%$ each. Atomic mass of ' $X$ ' is 20 and ' $Y$ ' is 40 . What can be its simplest formula?\

Professor PC Thomas Classes · Answer

(b) : Percentage of element ' $X$ ' $=50$, molar ratio $=\frac{50}{20} =2.5$\ Percentage of element ' $Y$ ' $=50$, molar ratio $=\frac{50}{40}=1.25$\  For ' $X$ ', simple ratio $=2.5 / 1.25=2$ For ' $Y$ ', \ simple ratio $=1.25 / 1.25=1$\ Formula $=X_{2} Y$\
