Answer: Carbon dioxide is a pure substance.

Explanation: A pure substance is defined when a substance has a single type of molecule. If more than 1 type of molecule is present in a substance, then it is considered as a mixture.

  • Soda is basically a mixture of water and carbon dioxide. More than 1 type of molecule is present.
  • Gasoline is a mixture of may gases. More than 1 type of molecule is present.
  • Salt water contains salt and water molecules, hence it is considered as a mixture.
  • Carbon dioxide has only 1 type of molecule which is CO_2 molecules. Hence, it is a pure substance.

Temp must be Kelvin
38 C = <span> <span> <span> 311.15 </span> </span> </span> K
Volume at STP = 8.50 liters * (273.15 / 311.15) * (725 / 760) =

The formula to use is:

Volume at STP = Present Volume * (273.15 / Present Temp °K) * (Present Pressure (Torr) / 760)
