Question

Titanium metal is used as a structural material in many high-tech applications such as in jet engines.

Answer 1

Answer:

a.$Cp=0.523$

b.$Cp=25.02\frac{J}{mol^\circ C}$

Explanation:

a. First, we solve the specific heat equation as follows:

$Q=mCp\Delta T\\Cp=\frac{Q}{m\Delta T}\\Cp=\frac{89.7J}{33.0g\times5.20^\circ C}=0.523$

b. Then, we use the molar mass of titanium to determine its molar heat capacity, as follows:

$Cp=0.523\frac{J}{g^\circ C}\times 47.87\frac{g}{mol}\\Cp=25.02\frac{J}{mol^\circ C}$
