AfilCa [17]

Answer:

Change in temperature of calorimeter is 4.52^{0}\textrm{C}

Explanation:

Molar mass of anethole = 148.2 g/mol

So, 0.950 g of anethole = \frac{0.950}{148.2}moles of anethole = 0.00641 moles of anethole

1 mol of anethole releases 5541 kJ of heat upon combustion

So, 0.00641 moles of anethole release (5541\times 0.00641)kJ of heat or 35.52 kJ of heat

7.854 kJ of heat increases 1^{0}\textrm{C} temperature of calorimeter.

So, 35.52 kJ of heat increases (\frac{1}{7.854}\times 35.52)^{0}\textrm{C} or 4.52^{0}\textrm{C} temperature of calorimeter

So, change in temperature of calorimeter is 4.52^{0}\textrm{C}
