Igneous Rocks are formed from the cooling of magma or lava.
When an electron moves from a higher energy shell to a lower one, energy in the form of light, more specifically a wavelength of a photon is released.
It states the fact, which we now know, that electrons are responsible for the chemical bonding. According to this theory, valency is the number of electrons present in the outermost energy shell of the atom. This energy shell is called valency shell.
Answer:
2.32 m
Explanation:
So, according to definition of mole fraction:

Mole fraction = 0.176
Applying values as:


So,



Also, Molar mass of toluene = 92.14 g/mol
Thus,
The formula for the calculation of moles is shown below:


Also, 1 g = 0.001 kg
So,

Molality is defined as the moles of the solute present in 1 kg of the solvent.
It is represented by 'm'.
Thus,

<u>Molality of benzene = 2.32 m</u>
