A student finds that 24.96 g of water at 24.9 °C (density= 0.9971 g/cm3) is required to completely fill an empty flask. The water is removed and completely dried; granular solid copper weighing 51.24 g is then added to the flask. With the copper present in the flask, it was determined that 19.24 g of water was required to fill the remaining space in the flask completely. Show all work and determine the following: A. Volume of the empty flask 24.96g / 0.9971= 25.03mL B. Volume of the copper 19.24g x 0.9971=19.18mL water 25.03mL – 19.18 mL = 5.84mL copper C. Density of the copper 51.24g / 5.84ml = 8.77g/ml D. If this flask could be filled completely with solid copper, what would be the mass of that copper?
