The mathematical expression for heat capacity at constant pressure is given as:
(1)
where, Q = heat capacity
= molar heat capacity at constant pressure
= change in temperature
n = number of moles
Therefore, =
=
Number of moles =
=
= 0.186 mole
Put the values in formula (1)
(conversion of degree Celsius into kelvin)
=
= 6.32 J /mol K
Hence, molar heat capacity of benzene at constant pressure =
Answer: 0.635 M
Explanation:
Molarity : It is defined as the number of moles of solute present per liter of the solution.
Formula used :
where,
n= Moles=
= volume of solution = 150 ml
as 1 mole of gives 3 moles of
ions
Thus molarity of =
Molarity of = 0.635 M
Answer:
59.2 grams
Explanation:
We are given that 70.4% of the weight of the total 200 g of the concentration is made up of nitric acid, the remaining information is not required to solve the problem. Since water and nitric acid are the only components of the solution, the total weight of water is given by:
There are 59.2 grams of water in this solution.
