Two elements `X(` atomic weight `=75)` and `Y(` atomic weight `=16)` combine to give a compound having `75.8%` X.` The formula of the compound is

Two elements A (Atomic mass = 75) and B(Atomic mass =16) combine to give a compound having 75.8% A. Calculate the relative number of atoms present in B.

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 :

A solid is formed by two elements P and Q. The element Q forms cubic close packing and atoms of P occupy two third of tetrahedral voids. The formula of the compound is
