Number of moles = 78.41
<h3>Further explanation </h3>The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
4.72 x 10²⁵ atoms of a substance, then moles :
Answer : The temperature of the chloroform will be,
Explanation :
First we have to calculate the mass of chloroform.
conversion used :
Now we have to calculate the temperature of the chloroform.
Formula used :
where,
q = amount of heat or energy = 1.46 kJ = 1460 J (1 kJ = 1000 J)
= specific heat capacity =
m = mass of substance = 110.958 g
= final temperature = ?
= initial temperature =
Now put all the given values in the above formula, we get:
Now we have to convert the temperature from Kelvin to Fahrenheit.
The conversion used for the temperature from Kelvin to Fahrenheit is:
As we know that, or,
...........(1)
Now put the value of temperature of Kelvin in (1), we get:
Therefore, the temperature of the chloroform will be,
