Two elements X and Y combine in gaseous state to form XY in the ratio 1: 35.5 by mass. The mass of Y that will be required to react with 2 g of X is (A) 7.1 g (B) 3.55 g (C) 71 g (D) 35.5 g

x y 1 :35.5 ⇒ 1 g of × reacts with y=35.5 g 2 g of × will react with y=2 × 35.5 g = 71 g

Q. Two elements X and Y combine in gaseous state to form XY in the ratio 1 : 35.5 by mass. The mass of Y that will be required to react with 2 g of X is

7.1 g

3.55 g

71 g

35.5 g

$x y$
$1 : 35.5$
$\Rightarrow 1 g$ of $\times$ reacts with $y = 35.5 g$
$2 g$ of $\times$ will react with $y = 2 \times 35.5 g$
$= 71 g$
