The true mass of glucose is 180.156 g/mol. The molar mass of glucose was found experimentally through its freezing point depression in pure water. The experimentally determined molar mass was 195.3 g/mol. Determine the percent error of the experimentally determined molar mass of glucose. Give the absolute value and with two decimal places.
