A 55.3 g sample of lead heated and then quenched in a 175g sample of water. During the quenching reaction the temperature of the water increases from room temperature, 25.0 °C, to 42.6 °C. Calculate the heat absorbed by the water given that the specific heat capacity of lead is 0.13 J/(g*°C) and the specific heat capacity of water is 4.184 J/(g*°C).

A) 0.13 kJ
B) 13 kJ
C) 18 kJ
D) 31 kJ

the correct answer would be d. hope this !

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

catya your not at all which answer i've seen you do this on another question!
