Ariel found the density of an unknown solid to be 24.3 g/cm3. Her teacher told her that something must have gone wrong with her measurements because her percent error was 30.0% too high. What was the actual or accepted density of her unknown solid?

  • chemistry -

    Just plug the numbers into the formula for percent error.
    (24.3-x/x) = 0.30
    Solve for x
