so what you do is you use the formula shown below:specific heat capacity = energy required / (mass * change in temperature) here ,energy required = 10.0°C Note that cal. is short form for °Cmass (m) = 3.1gchange in temperature (ΔT) = 17.9°C Note that "ΔT" means change in temperatureSo, plugging the values into the formula, we get,Specific heat capacity= [tex] \frac{10}{3.1*17.9} [/tex] = [tex]0.1802126509[/tex] = 0.1802 cal./g°C i rounded the answer to the fourth decimal point
