Diamonds are measured in carats, and 1 carat = 0.200 g. The density of diamond is 3.51 g/cm a. What is the volume of a 8.0-carat diamond? Volume = cm b. What is the mass in carats of a diamond measuring 3.2 mL? Mass = carats At room temperature the element bromine, Br2, is a liquid with a density of 3.12 g/cm. Calculate the mass of 250 mL of bromine. Mass = 9 What volume does 175 g of bromine occupy? Volume = ml Many times errors are expressed in terms of percentage. The percent error is the absolute value of the difference of the true value and the experimental value, divided by the true value, and multiplied by 100. Percent error true value - experimental value x 100 true value Calculate the percent error for the following measurements. a. The density of an aluminum block determined in an experiment was 2.67 g/cm'. (True value is 2.70g/cm. Percent error = b. The experimental determination of iron in iron ore was 16.63% (True value is 16.17%) yo Percent error A balance measured the mass of a 1.000-9 standard as 0.9934-9. Percent orror
