Answer:


C=2.45(J)/(g\°C)

Step-by-step explanation:

Hello there!

In this case, since the thermodynamic definition of heat in terms of mass, specific heat and temperatures is given by:


Q=mC(T_2-T_1)

We are to calculate the specific heat of the ethanol as shown below:


C=(Q)/(m(T_2-T_1))

Thus, by plugging it the given data we can obtain:


C=(4650J)/(250.0g(29.6-22.00\°C)) \\\\C=2.45(J)/(g\°C)

Regards!
