Question

Рассчитай молярную массу оксида цинка ZnO. Ответ: M(ZnO) =

Answer 1

Ответ:

65+16=81 г/моль

Объяснение:

M(zn)=65,4 при вычислении всегда округляем

тоесть будет 65

M(O2)=16

и просто это складываем так как атомов цинка и кислорода по одному

Answer 2

Calculating Molar Mass of Zinc Oxide (ZnO)

To calculate the molar mass of zinc oxide (ZnO), we need to consider the atomic masses of zinc (Zn) and oxygen (O) and then sum them up.

The atomic mass of zinc (Zn) is approximately 65.38 g/mol, and the atomic mass of oxygen (O) is approximately 16.00 g/mol. Therefore, the molar mass of zinc oxide (ZnO) can be calculated as follows:

M(ZnO) = 65.38 g/mol (for Zn) + 16.00 g/mol (for O) = 81.38 g/mol.

So, the molar mass of zinc oxide (ZnO) is approximately 81.38 g/mol.
