Agas cylinder contains exactly 15 moles of oxygen gas (o2). how many molecules of oxygen are in the cylinder? 4.01 × 1022 molecules 6.02 × 1023 molecules 9.03 × 1024 molecules 2.89 × 1026 molecules

A gas cylinder containing 15 moles of oxygen gas has molecules of oxygen in the cylinder.

The Avogadro number is used for calculating the number of molecules in 1 mole of an object.

Thus, 1 mole of gas = molecules.

So, if 1 mole of oxygen in a gas cylinder contain   molecules of oxygen.

The molecules of oxygen in 15 moles of the oxygen cylinder are:

1 mole = molecules

15 moles = molecules

15 moles = molecules

15 moles = molecules.

Thus, a gas cylinder containing 15 moles of oxygen gas has molecules of oxygen in the cylinder.
