When to round?!

Postby Elle_Bertuccelli_1B » Sat Dec 03, 2016 9:29 pm

When calculating pH and concentrations, do we wait to round until the end? I am confused because this is usually how it goes, but the solutions manual rounds every single step of the way.

Only round at the end.

If there is a multipart question: a) b) c)

Then give the unrounded and rounded answer for each part.

Use the unrounded answer from (a) in part (b), etc.

I think a student asked me this in my Friday review session which is recorded and online.
