Answer:
31.9178 °C is the final temperature of the water
Explanation:
Mass of benzene burned = 6.200 g
Moles of benzene burned =
According to reaction , 2 moles of benzene gives 6542 kJ of energy on combustion.
Then 0.0794 mol of benzene on combustion will give:
Mass of water in which Q heat is added = m = 5691 g
Initial temperature =
Final temperature =
Specific heat of water = c = 4.18 J/g°C
Change in temperature of water =
31.9178 °C is the final temperature of the water
