X and Y are two compounds of elements A and C l . Molar mass % of Cl Compound Molar mass % of Cl X 137 77.5 Y 208 85.1 Thus, X and Y are (A) ACl 3, ACl 4 (B) A 2 Cl 3, ACl 3 (C) ACl , ACl 2 (D) ACl 3, ACl 5

Let, X be ACl x leftharpoons A + xCl, Y be ACl y = A + yCl Moles mass of x=137 % of Cl in X =(35.5 x/137)=(77.5/100) x=3.0 % of Cl in Y =(35.5 y/208)=(85.1/100) ∴ y=5 Thus, x is ACl 3 . Y is ACl 5

Q. $X$ and $Y$ are two compounds of elements $A$ and $Cl .$ Molar mass $%$ of $Cl$

Compound Molar mass $%$ of $Cl$

X 137 77.5

Y 208 85.1

Thus, $X$ and $Y$ are

$A C l_{3}, A C l_{4}$

$A_{2} C l_{3}, A C l_{3}$

$A Cl, A C l_{2}$

$A C l_{3}, A C l_{5}$

Let, $X$ be $A C l_{x} ⇌ A + x Cl$ ,

$Y$ be $A C l_{y} = A + y Cl$

Moles mass of $x = 137$

$%$ of $Cl$ in $X = \frac{35.5 x}{137} = \frac{77.5}{100}$

$x = 3.0$

$%$ of $Cl$ in $Y = \frac{35.5 y}{208} = \frac{85.1}{100}$

$∴ y = 5$

Thus, $x$ is $A C l_{3} . Y$ is $A C l_{5}$
