Answer to Question #311827 in General Chemistry for nat

Question

1. 0.315 moles of butane (C₄H₁₀) was burned in a copper calorimeter containing 4500 g of water. The calorimeter weighs 2,500 g. The temperature was observed to increase by 3.15 °C. Calculate the molar heat of combustion of butane (HEAT OF COMBUSTION PER MOLE). The specific heat of copper and water are 0.386 J/g. °C and 4.18 J/g. °C respectively.

Answer 1

Molar heat of combustion

4500/2500×3.15

Ans=98.76
