Answer : The for the combustion of naphthalene is
Solution : Given,
Mass of naphthalene = 1.025 g
Initial temperature =
Final temperature =
Specific heat capacity of calorimeter =
Molar mass of naphthalene = 128 g/mole
First, we have to calculate the heat absorbed,
Formula used :
Now put all the given values in this formula, we get
Now we have to calculate the moles of naphthalene.
Moles of =
Now we have to calculate the for combustion of naphthalene.
where,
q = heat absorbed
n = number of moles
Now put all the values in this formula, we get
Therefore, the for the combustion of naphthalene is
