Lol thanks Borek :embarrassed:
2. ### A quick PPM question

Thanks! Just another thing, the answer came to be 1900ppm in 0.250L. I had to dilute it so that I took 0.01L from that solution and made it up to 0.1L. To find the ppm of the diluted solution is it as simple as dividing the ppm by 25? Because I took 1/25 of the solution? I'm not sure since...
3. ### A quick PPM question

Ah yeah I get what you mean. The question is asking to calculate the concentration of Fluoride in mg/L (PPM). I'm guessing this would lean to where the steering wheels mass is much less than the cars mass? So I need to use 19 (MW of F-) in the PPM equation? Since it's a 0.1M conc. of NaF...

Oh right! So the PPM of Fluoride still will be 4213.59? So it's like saying out of 50 cars you'll still only have 50 steering wheels? Do my calculations look ok? Thanks!
5. ### A quick PPM question

Homework Statement Calculate PPM of *Fluoride* in standard solution. NaF (dissolved in solution) = 1.0534g in 0.250L distilled water. Homework Equations PPM = Mol/L * g/mol * 1000 c=n/V n=m/M The Attempt at a Solution C=n/V, n = m/M n = 1.0534/41.99 = 0.02509 c = n/V =...
