If 11.9 kJ are used to heat a sample of water the temperature increases from 20.0°C to 650°C. Calculate the mass of the water
general formula

Explanation:

Hello!

In this case, since the energy involved during a heating process is shown below:

Whereas the specific heat of water is 4.184 J/(g°C), we can compute the heated mass of water by the addition of 11.9 kJ (11900 J) of heat as shown below:

Thus, by plugging in, we obtain:
