Chemistry - Mole Concept Question with Solution | TestHub

An element exist in two isotopic forms ${\mathrm{X}}^{120}$ and ${\mathrm{X}}^{122}$, in equal abundance. The average atomic mass of element is 121.44 . If each atom of ${\mathrm{X}}^{120}$ are 10.04 times heavier than one ${\mathrm{C}}^{12}$ atom, then how many times each atom of ${\mathrm{X}}^{122}$ is heavier than one ${\mathrm{C}}^{12}$ atom?
