1. You're the owner of a bar and have recently received a shipment of rum from a new supplier. You suspect that the bottles have been watered down. To test your suspicion, you weigh a bottle from the shipment using a kitchen scale. Empty 1 L Bottle 521.631 g Full bottle 1436.799 g a) What is the mass of the liquid in the bottle? Report the mass to the correct number of significant figures. (1 pt) b) If the volume of liquid in the bottle is 0.998 L. What is the density of the rum in the bottle? Report the density in g/mL to the correct number of significant figures. (1 pt) c) The label on the bottle claims the rum is 150-proof. This means that the rum contains 75% ethanol by volume. What volume of ethanol is in 0.998 L of rum? Report the volume in milliliters to the correct number of significant figures. (1 pt) d) If the density of ethanol is 0.785 g/mL. What should the mass of 0.998 L of rum be in grams if it contains 75% ethanol? Assume that the remainder of the rum has a density equivalent to water which is 0.997 g/mL. (2 pts) e) What is the true density of 150-proof rum? Report the density in g/mL to three decimal places. (1 pt) f) You test three more bottles and come up with the following results: Bottle Density (g/mL) 0.920 2 0.915 3 0.923 WNHI g) What is the average density of the three bottles? Report the density to 3 decimal places. (1 pt) h) What is the average deviation? Report the average deviation to 3 decimal places. (1 pt) i) Based on the results of your testing. Is it reasonable to believe that the supplier has sold you watered down (under-proof) rum? (1 pt)
