A rock with a mass of 489 g in air is found to have an apparent mass of 308 g when submerged in water. (a) What mass (in g) of water is displaced? g (b) What is the volume (in cm3) of the rock? cm3 (c) What is its average density (in g/cm3)? g/cm3 Is this consistent with the value for granite? Yes O O No
2. An insoluble, nonreactive solid metal sphere weighing 21.52 g is added to 28.7 mL of water in a graduated cylinder. The water level rises to 32.8 ml. Calculate the density of the metal.
1.05 g of NaOH pellet is added to 45 mL of distilled water and the temperature rises from 25.1 oC to 35.8 oC. Determine the heat per mole of NaOH generated in this process. Assume that the density of water is 1 g/mL and the specific heat capacity of the solution is 4.184 J/goC
When 25 g of the unknown metal were added, the water was displaced 3.50 mL. Calculate the density of the unknown metal. Remember, density = mass/volume. Express your answer as g/cm3 ( 1 mL = 1 cm3). Choose the closest answer. How many significant figures should be shown in the final answer?
