Molar and molecular weight of ZnSe

• Relative molecular weight of ZnSe: 144.369
• Molar mass of ZnSe: 144.369 g/mol (0.14437 kg/mol)

Calculation of the relative molecular and molar mass of ZnSe

• Mr[ZnSe] = Ar[Zn] + Ar[Se] = 65.409 + 78.96 = 144.369
• Molar mass (kg/mol) = Mr[ZnSe] : 1000 = 144.369 : 1000 = 0.14437 kg/mol

ZnSe: percent composition by element

• Zinc (Zn) = 65.409 : 144.369 * 100 = 45.307 %
• Selenium (Se) = 78.96 : 144.369 * 100 = 54.693 %
