Ppm concentration

  1. Mar 6, 2016 #1
    1. The problem statement, all variables and given/known data
    An aqueous solution is found to be 0.0050% Ag+ ions. Calculate the ppm concentration of the solution.

    2. Relevant equations
    1mg / 1 L

    3. 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,

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

    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?
