# What is the molecular weight of SO4?

Jan 18, 2016

$96.064 \frac{g}{m o l}$

#### Explanation:

To determine a compound's molecular weight, you simply have to add all the atomic weights of the elements involved.

For $S {O}_{4}$,

$M W S {O}_{4} = \left(32.066 \frac{g}{m o l}\right) + \left(15.9994 \frac{g}{m o l}\right) \left(4\right)$
$M W {O}_{4} = 96.064 \frac{g}{m o l}$
