Answer:
1.4200 g
Explanation:
The chlorine gas has a molecular formula Cl2. In table periodic, the molar mass of one atom of chlorine is 35.5 g/mol, so the molar mass of Cl2 is 71 g/mol.
Molar mass, mass and number of moles are related by the equation below:
Where n is the number of moles, m is the mass, and MM is the molar mass of the compound.
So, for 0.0200 moles of Cl2 produced:
m = 71x0.0200
m = 1.4200
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
