To calculate the molar mass of zinc oxide (ZnO), we add the atomic masses of zinc (Zn) and oxygen (O).

  • The atomic mass of zinc (Zn) is approximately 65.38 g/mol.
  • The atomic mass of oxygen (O) is approximately 16.00 g/mol.

Now, we can calculate the molar mass of zinc oxide:

\[ \text{Molar mass of ZnO} = \text{Molar mass of Zn} + \text{Molar mass of O} \] \[ \text{Molar mass of ZnO} = 65.38 , \text{g/mol} + 16.00 , \text{g/mol} \] \[ \text{Molar mass of ZnO} = 81.38 , \text{g/mol} \]

Therefore, the value closest to the molar mass of zinc oxide is 81.38 g/mol.
