Answer:

m = 50.74 kg

Step-by-step explanation:

We have,

Initial temperature of water is 20 degrees Celsius

Final temperature of water is 46.6 degrees Celsius

Heat absorbed is 5650 J

It is required to find the mass of the sample. The heat absorbed is given by the formula ad follows :


Q=mc\Delta T

c is specific heat of water, c = 4.186 J/g°C

So,


m=(Q)/(c\Delta T)\\\\m=(5650)/(4.186* (46.6-20))\\\\m=50.74\ kg

So, the mass of the sample is 50.74 kg.
