A student uses the density experiment you just completed and they determine the density of silver to be 9.3g/mL. What is their % error based on the equation shown below? (The "true value" for the density of silver is 10.5g/mL.) Percent Error = |Observed value True Value|| X 100 True Value very close 1% 55% 11% The density of isopropyl alcohol which is used in rubbing alcohol is 0.79 g/ml.
