Ppm concentration

[brycenrg]

Homework Statement

An aqueous solution is found to be 0.0050% Ag+ ions. Calculate the ppm concentration of the solution.

Homework Equations

1mg / 1 L

The Attempt at a Solution

0.0050%/100 = 0.00005g
Assuming there is 1 L of solution

.00005g *(1/1000)

0.00000005 mg/L

1mg/L = 1 ppm

0.00000005 ppm

Hi brycenrg:

I don't understand your attempt at a solution. Can you explain the steps?

I also don't understand the notation: 0.0050% Ag% ions. What do the percent signs mean?

Regards,
Buzz

The percent is the amount of Ag ions of the whole solution, pretty sure

0.0050%/100 = 0.00005g

Doesn't make much sense to me. Where did the g come from? Is it 0.00005g in 1 L, in 100 L, in any volume?

You are right about assuming 1 L of a solution. What would be its approximate mass?
