L solution
=
1.25 moles NaCl
Now, to convert this to grams of sodium chloride, you must use the mass of
1
mole of this compound as a conversion factor. The mass of
1
mole of sodium chloride is given by its molar mass
1.25

When the oxygen atoms in ozone layer were destroyed by ultraviolet radiations the individual oxygen atoms will make bond with each other and form paired oxygen molecules again to form ozone.
What is the ozone layer?
Ozone layer has a high concentration of ozone (O3) in comparison to the rest of the atmosphere, although it is still low in comparison to other gases in the stratosphere.
The ozone layer contains less than ten parts per million of ozone, whereas the normal ozone concentration in the Earth's atmosphere is around 0.3 parts per million. The ozone layer is mostly found in the lower stratosphere.
