The δhcomb value for anethole is -5539 kj/mol. assume 0.840 g of anethole is combusted in a calorimeter whose heat capacity (calorimeter) is 6.60 kj/°c at 20.6 °c. what is the final temperature of the calorimeter

Final temperature of calorimeter is 25.36^{0}\textrm{C}

Explanation:

Molar mass of anethole = 148.2 g/mol

So, 0.840 g of anethole = of anethole = 0.00567 moles of anethole

1 mol of anethole releases 5539 kJ of heat upon combustion

So, 0.00567 moles of anethole release of heat or 31.41 kJ of heat

6.60 kJ of heat increases temperature of calorimeter.

So, 31.41 kJ of heat increases or temperature of calorimeter

So, the final temperature of calorimeter =
