Answer: There are molecules
gas are in 756.2 L.
Explanation:
It is known that 1 mole of any gas equals 22.4 L at STP. Hence, number of moles present in 756.2 L are calculated as follows.
According to mole concept, 1 mole of every substance contains molecules.
Therefore, molecules of S present in 33.76 moles are calculated as follows.
Thus, we can conclude that there are molecules
gas are in 756.2 L.
Answer:
The frequency is
Explanation:
From the question we are told that
The energy required to ionize boron is
Generally the ionization energy of boron pre atom is mathematically represented as
Here is the Avogadro's constant with value
So
=>
Generally the energy required to liberate one electron from an atom is equivalent to the ionization energy per atom and this mathematically represented as
=>
Here h is the Planks constant with value
So
=>
