It takes 723 J of energy to change 25,0 g of a substance by 35.0°C. What is the specific heat of the substance? Report your answer with an appropriate number of significant figures, J/g°C​

thats how its supposed to be

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

ok whats the question if not i cannot you i need question and need a thing to answer
