Question

Consider the following data :
Element Atomic weight
X
14
Y
16
X and Y combine to form a new substance Z. If four moles of Y
combine with two mole of X to give one mole of Z, then the mass of
one mole of Z is
g.​

Answer 1

Answer:

I thin the answer should be 92

Explanation:

2X + 4Y ---> Z

Since 2 moles of X (Total Weight=28) combine with 4 moles of Y (Total Weight=64) to give one mole of Z therefore weight of one mole of Z=28+64=92
