Two elements X (atomic mass 16) and Y (atomic mass 14) combine to form compounds A,B and C. The ratio of different masses of Y which combines 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.
