Know this.
1 moles of a gas contains 6.022x10²³molecules.
Given: 48g of Oxygen gas.
Find the moles present
Mole = Mass/Molar Mass
Molar Mass of O2 = 16x2 =32g/mol
Mole = 48/32
=1.5moles of O2.
Recall
1 moles of gas contains 6.022x10²³molecules
1.5moles would contain
1.5 x 6.022x10²³molecules
=9 . 0 3 3 x 1 0 ² ³ molecules of Oxygen gas .
