(C) To find the simplest formula,we calculate the mole ratio of the elements:Moles of $X = \frac{50}{10} = 5 \text{ mol}$Moles of $Y = \frac{50}{20} = 2.5 \text{ mol}$Now,divide by the smallest number of moles to get the simplest ratio:Ratio of $X : Y = \frac{5}{2.5} : \frac{2.5}{2.5} = 2 : 1$Therefore,the simplest formula is $X_2Y$.
