🤓 Based on our data, we think this question is relevant for Professor Brown's class at HUMBOLDT.
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
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
