Chemical Composition of Cu(NO₃)₂

Understanding the chemical makeup of copper(II) nitrate is essential for calculating its molecular weight. The compound consists of:

One copper (Cu) atom
Two nitrate (NO₃) groups

Atomic and Molecular Weights of Constituent Elements

Copper (Cu): approximately 63.55 g/mol
Nitrogen (N): approximately 14.01 g/mol
Oxygen (O): approximately 16.00 g/mol

Calculating the Molecular Weight of Cu(NO₃)₂

Step-by-Step Calculation

Cu: 1 atom × 63.55 g/mol = 63.55 g/mol
Each nitrate (NO₃): (14.01 for N) + (3 × 16.00 for O) = 14.01 + 48.00 = 62.01 g/mol
Since there are two nitrate groups: 2 × 62.01 = 124.02 g/mol
Total molecular weight = Copper + Nitrate groups
Total = 63.55 + 124.02 = 187.57 g/mol
