The degradation of CF3CH2F (an HFC) by OH radicals in the troposphere is first order in each reactant and has a rate constant of k=1.6×108M−1s−1 at 4∘C.

If the tropospheric concentrations of OH and CF3CH2F are 8.1×105 and 6.3×108 molecules cm−3, respectively, what is the rate of reaction at this temperature in M/s?

Express your answer using two significant figures.

If you can show work please that would be fantastic!

rate = k(CF3CH2F)(OH)
Okay... I already know that. I plugged in all the numbers and I get 8.2*10^22, which is not the right answer. Can someone show the work for the problem please?
molecules is not M. I would convert molecules to mol which will be mols/cc and convert that to mols/L which is M.
