Question

What is the molecular weight of SO4?

Answer 1

`96.064 g / [mol]`

Explanation:

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

For `SO_4`,

`MW SO_4 = (32.066 g/[mol]) + (15.9994 g/[mol])(4)`
`MW O_4 = 96.064 g/[mol]`
