Hint: We have to remember that a mole is characterized as the mass of the substance which comprises the equivalent amount of essential units.
Example: The number of molecules in twelve grams is equivalent to $12$ carbons. The essential units can be particles, molecules or equation units dependent on the substance.
Complete step by step answer:
Given:
The mass of water is $36g$.
We know that the molecular mass of water is $18g/mol$.
Formula used:
$n = \dfrac{{{\text{Mass of substance}}}}{{{\text{Molar mass}}}}$
One can calculate the number of moles in a substance using the above formula.
The number of moles in $36g$ of water is calculated as,
$n = \dfrac{{36g}}{{18g/mol}} = 2 moles$
Hence, the number of moles in $36g$ of water is two moles.
Additional information: The quantity of chemical substance in a reaction is given mole fraction. One mole of any substance is equivalent to Avogadro number. The value of Avogadro number is \[6.023 \times {10^{23}}\]. It very well may be utilized to gauge the items acquired from the compound reaction. The unit is meant by mole.
Note: We have to remember that the mole is basically an amount of particles. Usually the particles checked are chemically indistinguishable elements, and exclusively particular.
If a solution contains a specific number of broken up atoms that are pretty much autonomous of one another.
