The correct answer is:
$X_2 Y$
\(\begin{array}{lllll}
\text {Element } & \%(\mathrm{a}) & \text {At.wt.() }& \mathrm{a} / \mathrm{b} & \text {Ratio } \\
X & 50 & 10 & 5 & 2 \\
Y & 50 & 20 & 2.5 & 1
\end{array}\)
Simplest formula \(=X_2 Y\)
\text {Element } & \%(\mathrm{a}) & \text {At.wt.() }& \mathrm{a} / \mathrm{b} & \text {Ratio } \\
X & 50 & 10 & 5 & 2 \\
Y & 50 & 20 & 2.5 & 1
\end{array}\)
Simplest formula \(=X_2 Y\)
