🤓 Based on our data, we think this question is relevant for Professor Brown's class at HUMBOLDT.
For this problem, we’re being asked to determine the number of carbon dioxide (CO2) molecules found in 20.00 g CO2. The flow for this problem will be like this:
Mass of CO2(molar mass of CO2) → Moles of CO2 (Avogadro’s number) → Molecules of CO2
If you have 20.0 g of carbon dioxide gas, how many molecules of CO 2 do you have?
A) 4.30 x 1023 molecules of CO2
B) 2.74 x 1023 molecules of CO2
C) 5.30 x 1026 molecules of CO2
D) 1.46 x 10-21 molecules of CO2
E) 7.55 x 10-25 molecules of CO2
