Spectrophotometry Example

[soliveirajr]

Doesn't spectrophotometry have more to do with light colors (frequencies) than absorbance?

Thanks a lot Sal! I read recently that breath analyzers work using spectrophotometry, so I was willing to learn more about it....

shouldn't the answer be 0.010 mol/L??? significant figures...

@hossein1413 you are right if epslion is 5.4 (which I wrote down in the calculation). We calculated it however to be 5.40 in the step before so I just went with 3 significant digits. Hope that helps. Sorry for the confusion.
