A metal has a heat capacity of 0.0562 cal/g oC. If 190.0 calories of heat are added to a 125 gram sample of the metal, what will be the temperature change?

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

you need to have a picture of the atom that way we can answer it
