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