# What is the molar mass of copper (II) chloride?

Mar 20, 2018

Approximately $134.446$ g/mol

#### Explanation:

Copper (II) Chloride, or $C u C {l}_{2}$, is composed of Copper ($C u$) and Chloride ($C {l}_{2}$).

We can find the molar mass by adding up the molar mass of Copper, and adding it to that of Chlorine times two (because of the subscript).

Molar Mass can be found on the Periodic Table (most likely under "Atomic Weight"). Thus, we have

Copper: $63.546$ g/mol (approximately)
Chloride: $2 \left(35.45\right) = 70.9$ g/mol (approximately)

$\implies 63.546 + 70.9 = 134.446$

Therefore, the molar mass of Copper (II) Chloride is approximately $134.446$ g/mol.

NOTE: g/mol =grams per mole
