Calculate the percent error on each (round to the nearest percent): 1. A students measures the density of iron to be 10.50 g/mL. The true density for iron is 11.34g/mL. What would be the percent error of the experiment? 2. The molar mass of zinc is known to 65.409 grams/mol. My measurement shows it to be 63.238 grams/mol. What is my percent error? 3.1 measure a 15.00 mL sample, and I get 14.65 mL. What is my percent error? NEWS
