Question

A solution is labelled 2.89ppm and is made with a solute that has moles in an equal to 5.22g/mL. What is molarity in solution?

Answer 1

You will have to respecify this question...

Explanation:

`"Molarity"="Moles of solute"/"Volume of solution"`

`"ppm"-="milligrams of solute per litre of solution"`...this is normally used for low concentrations...and in one litre of water there are `"1,000,000 milligrams"`, hence `"parts per million"`..

Here, we don't know the molar mass. But if concentration is in the `"ppm"` range, the molarity of the solution is likely to be low to negligible.

Answer 2

the molarity is 0.000554

Explanation:

Given:

concentration of the solute in ppm is `2.89`
ie,

`2.89"gms of solute in " 1000000" mL of solution"`

Also, it is known that

amount of solute in `1 ml` is `5.22 gms`

To find the molarity of the solution

`"Molarity "=("Mass of the solute")/("Volume of solution in litre")`

Given as `"5.22 gms in a mL"`

ie

`"5.22"xx"1000 gms in litre"=5220gL^-1`
`2.89"gms are present in" 2.89/5220L=0.000554L`

Hence, the molarity is 0.000554
