Question

unit exam - covalent compounds
8 o 16.00
17 cl 35.45
what is the molar mass of the covalent compound clo4?
clo4 = ? $\frac{g}{mol}$

Explanation:

Step1: Identify molar - mass of elements

The molar mass of Cl is 35.45 g/mol and of O is 16.00 g/mol.

Step2: Calculate molar mass of \(ClO_4\)

There is 1 Cl atom and 4 O atoms in \(ClO_4\). The molar mass \(M\) of \(ClO_4\) is \(M = 35.45+4\times16.00\).
\[M=35.45 + 64.00=99.45\]

Answer:

99.45
