Hint : To calculate the number of moles of the oxygen molecule. We must know the formula that is being used. So, the formula to calculate number of moles is $ \dfrac{{mass\;of\;the\;given\;substance}}{{molar\;mass}} $
Complete Step By Step Answer:
A mole is characterized as the mass of the substance which comprises the equivalent amount of essential units. Model molecules in $ 12 $ grams are equivalent to $ 12c $ . The fundamental units can be particles, ions or equation units dependent on the substance.
A mole portion shows the quantity of substance components. One mole of any substance is equivalent to the estimation of $ 6.023 \times {10^{23}} $ (Avagadro number). It tends to be utilized to quantify the items obtained from the synthetic response. The unit is indicated by mol.
Avogadro's number is a very important relationship to remember: $ 1mole = 6.022 \times {10^{23}} $ atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number.
We know the formula of the number of moles.
$ = $ $ \dfrac{{given\;mass}}{{molar\;mass}} $ .
We have given mass that is $ 320g $ , and we know the molar mass of the oxygen is $ 32g $ .
Now, let’s put the values in the formula
$ = \dfrac{{given\;mass}}{{molar\;mass}} = \dfrac{{320g}}{{32g}} $ .
So, the number of moles of oxygen molecules in $ 320g $ of oxygen gas is $ 10g $ .
Note :
The mole is an action or the base unit for the measure of substance present in the given example. $ 1 $ mole is a number which is equivalent to $ 6.022 \times {10^{23}} $ particles, otherwise called the Avogadro's consistency. These particles can be any sort of species, example ions, atoms, electrons, protons, neutrons and so forth.
