Suppose two elements X and Y combine to form two compound `XY_2 and X_2Y_3`weighs `85g`. The atomic masses of X and Y are respectively :

Suppose two elements X and Y combine to form two compounds XY_(2) and X_(2)Y_(3) when 0.05 mole of XY_(2) weight 5g while 3.011xx10^(23) molecules of X_(2)Y_(3) weight 85g . The atomic masses of X and Y are respectively.

Suppose elements X and Y combine to form two compounds XY_(2) and X_(3)Y_(2) when 0.1 mole of former weigh 10 g while 0.05 mole of the latter weigh 9g . What are the atomc weights of X and Y .

Two elements X and Y combine to form a compound XY. Under what conditions the bond formed between them will be ionic ?

Two elements X (at.mass 16) and Y (at.mass 14) combine to form compounds A,B and C . The ratio be different masses of Y which combine with a fixed mass of X in A,B and C is 1 : 3 : 5. If 32 parts by mass of X combines with 84 parts by mass of Y in B then in C,16 parts by mass of X will combine with ...... parts by mass of Y :

Two elements P and Q combine to form two different compounds in stoichimetric ratios of 1:2 and 1:3.If 0.25 mole of 1^(st) compound weighs 16 g and 0.05 mole of 2^(nd) compound weighs 4 g, then the atomic weighs of P and Q respectively are

A compound contains elements X and Y in 1 : 4 mass ratio. If the atomic masses of X and Y are in ratio 1 : 2, then empirical formula will be

The elements X and Y form compound having molecular formula XY_(2) and XY_(4) (both are non - electrolysis), when dissolved in 20 g benzene, 1 g XY_(2) lowers the freezing point by 2.3^(@)c whereas 1 g of XY_(4) lowers the freezing point by 1.3^(C) . Molal depression constant for benzene is 5.1. Thus atomic masses of X and Y respectively are

X and Y are two elements which form X_(2)Y_(3) and X_(3)Y_(4) . If 0.20 mol of X_(2)Y_(3) weight 32.0g and 0.4mol of X_(3)Y_(4) weigths 92.8g , the atomic weights of X and Y are respectively

If the two lines of regression are 2x-y-4=0 and 9x-2y-38=0 , then the means of x and y variates respectively are
