Zn(No2)2 Molar Mass

The molar mass of the compound Zn(NO2)2 is calculated as follows:

- The atomic weight of Zn (zinc) is 65.38 g/mol.

- The molecular weight of NO2 (nitrite ion) is calculated by adding the atomic weights of nitrogen and oxygen, which are 14.01 g/mol and 16 g/mol respectively. Thus, the molecular weight of NO2 is 14.01 + 2(16) = 46.01 g/mol.

- Since there are two NO2 groups in the compound, the total molecular weight is 65.38 + 2(46.01) = 157.4 g/mol.

Therefore, the molar mass of Zn(NO2)2 is 157.4 g/mol.
