Question: Determine the final temperature of a gold nugget (mass = 376 g) that starts at 288 K and loses 4.85 kJ of heat to a snowbank when it is lost. The specific heat capacity of gold is 0.128 J/gºC. Select one: O A 288 K O B. 389 K O C. 187K OD. 133 K O E. 377 K Which of the following statements is TRUE? Select one: O A. The principal quantum number (n). An example would be 31.75 mL - 1.325 mL = 30.425 mL. In order to find the density, I simply divided the mass found by the volume found. For example, 30.0035 g divided by 30.425 mL equals 0.9861 g/mL. To find the average density, I added the three densities I found, then divided that total by three to find the average.
