Question

The densities of three aliquots of an unknown solution were found to be 1.028 g/mL, 1.043 g/mL, and 1.039 g/mL. Calculate the average density of this unknown solution?

Answer 1

`=1.037(g)/(mol)`

Explanation:

Average simply mean the value obtained from the summations of the densities divided by the number of three aliquot samples; that is,
`=(1.028(g)/(ml)+1.043(g)/(ml)+1.039(g)/(ml))/3`
`=(1.037g)/(mol)`
