A cube of aluminum (Cp = 0.897 J/g. K) has a temperature of 325 K. It is placed in a beaker of cold water
If the aluminum cools to 301 Kas the water absorbs 815.7 J of heat, what is the mass of the cube?

c8h10 is your answerr

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

it is b that is the answer.
