Question

molar mass of ionic compounds
8 o 16.00
29 cu 63.55
what is the molar mass of the ionic compound cuo?
cuo = ? $\frac{g}{mol}$

Explanation:

Step1: Identify molar - mass of elements

The molar mass of Cu is 63.55 g/mol and of O is 16.00 g/mol.

Step2: Calculate molar mass of CuO

For CuO, there is 1 Cu and 1 O atom. So, molar mass of CuO = molar mass of Cu+ molar mass of O.
$M_{CuO}=63.55 + 16.00$
$M_{CuO}=79.55$ g/mol

Answer:

79.55
