An element can be identified through its molecular mass.
The mole is the chemical unit for the amount of a substance and serves as the bridge that connects grams to molecules, atoms, formula units and ions.
Avogadro’s number gives the value of atoms/particles/ions in each mole. 1 mol is equal to 6.022x1023 number of atoms or particles or ions.
If 2.26x1022 atoms of element Y have a mass of 1.50 g, what is the identity of Y?
