Strategy:
 According to Avogadro’s Hypothesis, a sample containing an equal number of molecules of two gases must contain an equal number of moles of those gases. The volume of the sample is irrelevant; we simply need to equate the moles of Oxygen and Carbon Dioxide.

Step 1: Calculate moles of Oxygen
Molar mass of .

Step 2: Find mass of } \ce{CO2} 	ext{ for equal moles
For equal molecules, moles of  must be .
Molar mass of .
