Here's how to calculate the number of moles of carbon dioxide molecules in the bottle:

1. Find the molar mass of carbon dioxide (CO2):

* Carbon (C): 12.01 g/mol

* Oxygen (O): 16.00 g/mol

* CO2: 12.01 + (16.00 x 2) = 44.01 g/mol

2. Calculate the number of moles:

* Moles = mass / molar mass

* Moles = 44.009 g / 44.01 g/mol

* Moles ≈ 1.000 mol

Therefore, the bottle contains approximately 1.000 moles of carbon dioxide molecules.
