What is the Molar Mass of Zn(NO3)2?

The molar mass of Zn(NO₃)₂ (Zinc Nitrate) is calculated by adding the atomic masses of all the atoms in the compound. Here’s how it’s done:

• Zinc (Zn): 65.38 g/mol
• Nitrogen (N): 14.01 g/mol
• Oxygen (O): 16.00 g/mol

Zinc Nitrate has one zinc atom, two nitrogen atoms, and six oxygen atoms. The calculation is as follows:

Molar Mass = (1 × 65.38) + (2 × 14.01) + (6 × 16.00)

Molar Mass = 65.38 + 28.02 + 96.00

Molar Mass = 189.40 g/mol

Therefore, the molar mass of Zn(NO₃)₂ is 189.40 g/mol.
