## Homework Statement

I need to know the concentration in ppm of a standard Fe2+ solution. (diluted)

Here is the data I have.

I have 0.1964 g of Fe solution

the purity is 99.7%

The original solution was the above # of g in 250ml water.

10ml of this was then pipetted into a 100ml volumetric flask and diluted.

I have to find the concentration in ppm of this diluted solution using the info from the starting solution.

## Homework Equations

Don't think there are any. Just need logic to figure it out, of which I am limited in.

## The Attempt at a Solution

196.4mg/0.250L

=785.6 mg/L

*(10ml/100ml)

=78.56 ppm

This is what I have, but I don't think it's right because 78.56 ppm is not in the range of the spectrometer we used. Also, I didn't use the 99.7% purity anywhere.

Thanks.
