Use dimensional analysis to solve this problem. First calculate the molecular mass of CO2. This is found by (use a periodic table) adding 12.011g of C to (15.999g x2) grams of Oxygen. Once you do that, you find out that 44.009g are in 1 mole of CO2. Now, simply by looking at the equation of CO2, we can tell that 2 moles of oxygen atoms are in 1 mole of Co2 (look at the subscript for Oxygen). Now, your dimensional analysis should look like this: 254g CO2 x 1 mole CO2/44.009g CO2 x 2 mole Oxygen/1 mole CO2 The answer is 11.5 moles of Oxygen in 254g of CO2.
The conversion factor from pounds-mass (lbm) to pounds-mole (lbmol) is the molecular weight of the substance in pounds per mole.
The conversion factor from grams per mole (g/mol) to pounds mass per pound mole (lbm/lbmol) is 0.00220462.
254g is 0.56 pounds.
The conversion factor from grams per mole (g/mol) to daltons is 1 g/mol 1 dalton.

Three common conversion factors used in mole conversions are Avogadro's number (6.022 x 10²³ particles/mole), which relates moles to the number of atoms or molecules; the molar mass (grams/mole) of a substance, which converts between grams and moles; and the ideal gas law, where 1 mole of an ideal gas occupies 22.4 liters at standard temperature and pressure (STP). These factors facilitate conversions between different units when dealing with chemical quantities.
Three common conversion factors used in mole conversions are: Avogadro's Number: 1 mole = (6.022 \times 10^{23}) particles (atoms, molecules, etc.). Molar Mass: The mass of one mole of a substance in grams, expressed in g/mol (e.g., for water, it's approximately 18 g/mol). Volume at STP: For gases, 1 mole occupies approximately 22.4 liters at standard temperature and pressure (STP).
