How many moles of aspirin are present in 100 mg of aspirin? Enter your answer in scientific notation.

5.5E-4

  • chemistry -

    or should it be rounded to 5.6?

  • chemistry -

    I have 5.5507E-4. You are allowed 3 s.f. from the 100 so I would round that to 5.55E-4. I think you shorted yourself 1 place that you should keep.

  • chemistry -

    If allowed only two s.f. I would have rounded to 5.6E-4.
