gas.
What are moles?
A mole is defined as 6.02214076 × [tex]10^{23}[/tex]of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
The number of molecules in 16 grams of oxygen gas is 3.01 x [tex]10^{23}[/tex], equal to half of Avogadro's number.
So, 0.470 g of oxygen gas contains
= (3.01 x [tex]10^{23}[/tex] x 0.470 g ) ÷ 16
= 0.08841875 x [tex]10^{23}[/tex]
Hence, 0.08841875 x [tex]10^{23}[/tex] molecules are present in 0.470 g of oxygen
gas.
