Molar and molecular weight of CaSe

• Relative molecular weight of CaSe: 119.038
• Molar mass of CaSe: 119.038 g/mol (0.11904 kg/mol)

Calculation of the relative molecular and molar mass of CaSe

• Mr[CaSe] = Ar[Ca] + Ar[Se] = 40.078 + 78.96 = 119.038
• Molar mass (kg/mol) = Mr[CaSe] : 1000 = 119.038 : 1000 = 0.11904 kg/mol

CaSe: percent composition by element

• Calcium (Ca) = 40.078 : 119.038 * 100 = 33.668 %
• Selenium (Se) = 78.96 : 119.038 * 100 = 66.332 %
