Answer:

Ok.

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

=9.033 x 10²³ molecules of Oxygen gas.

Have a great day!
