# accuracy of an experiment determined? What is density and how will it be used in the Measurements Experiment? 2. You are asked by the King of Allegesia to determine if the crown he was given for his birthday is pure gold. The density of pure gold is 19.32 g/mL; the density of water is 0.998 g/mL at 20°C. There is a container when filled to mark contains 1900.0 mL. When the container is filled with water to the mark, it has a mass of 2499.5 g. The crown is placed in the container and filled to mark with water and now weighs 15,113.3 g. The crown has a mass of 13,910.0 g. What is the density of the crown? Is the crown pure gold? 3. Linus Pauling (recipient of 2 Nobel Prizes, one for Chemistry and another for Peace) wrote a book, '"Vitamin C and the Common Cold", which proposed that large doses of vitamin C can cure the common cold. One commercial over-the-counter production consists of 500.0 mg tablets that are 20.0 % by mass Vitamin C. How many of these tablets are need for a 1.00 g dose of vitamin C? Each 500.0 mg tablet costs 2 cents. If you can take a 1000.0 mg table of pure vitamin C for 9 cents a tablet, which would be more cost effective?
