Elements X and Y form two non-volatile compounds (XY. and XY3). When 10 g of XY is dissolved in 50 g of ethanol, the depression in freezing point ( ∆Tf ) was 5.333 K . When 10 g of XY3 is dissolved in 50 g of ethanol, the was (∆Tf)2.2857 K . What are the atomic weights of X and Y respectively ? (Kf=2K‌kg‌mol−1)
