Chemistry Problem involving specific heat capacity and energy change

Click For Summary
SUMMARY

The discussion centers on a chemistry problem involving the calculation of the volume of a gold cube based on its specific heat capacity and energy transfer with water. The gold cube is heated to 94.2 degrees Celsius and submerged in 31.3 mL of water initially at 28.7 degrees Celsius, reaching a final temperature of 45.6 degrees Celsius. The specific heat capacity of gold is given as 0.130 J/g°C, and its density is 19.3 g/mL. The solution involves calculating the energy required to heat the water and using that energy to determine the mass of gold, which can then be converted to volume using the density of gold.

PREREQUISITES
  • Understanding of specific heat capacity and its formula
  • Knowledge of energy transfer in thermal systems

Homework Statement


A cube of gold is heated to a temperature of 94.2 degrees celsius, and then submerged in 31.3 mL of water at an initial temperature of 28.7 degrees celsius. If the final temperature of the water is 45.6 degrees celsius, calculate the volume of the cube of gold (s=0.130, density = 19.3 g/mL)


Homework Equations





The Attempt at a Solution



I don't really know where to start however, what if I found how much energy is required to heat water from 28.7 to 45.6 degrees celsius and then used that amount (q) to find the mass of gold using the specific heat capacity of gold? Any suggestions would be greatly appreciated, thanks

Where is the problem with finding volume of the cube once you know its mass and the gold density?
