Carbon dioxide is a gaseous molecule made up of the elements, C and O. Each mole of carbon dioxide has one mole C and two mole oxygen atoms.
Molar mass of carbon dioxide (
)=![(1 * 12.01\frac{g}{mol}) +(2* 16\frac{g}{mol})=44.01\frac{g}{mol}](https://tex.z-dn.net/?f=%281%20%2A%2012.01%5Cfrac%7Bg%7D%7Bmol%7D%29%20%2B%282%2A%2016%5Cfrac%7Bg%7D%7Bmol%7D%29%3D44.01%5Cfrac%7Bg%7D%7Bmol%7D)
Percentage by mass of carbon = ![\frac{(1*12.01\frac{g}{mol}) }{44.01\frac{g}{mol} } *100=27.3%](https://tex.z-dn.net/?f=%5Cfrac%7B%281%2A12.01%5Cfrac%7Bg%7D%7Bmol%7D%29%20%7D%7B44.01%5Cfrac%7Bg%7D%7Bmol%7D%20%7D%20%2A100%3D27.3%25)
Percentage by mass of oxygen = ![\frac{(2*16\frac{g}{mol})}{44.01\frac{g}{mol} } *100=72.7%](https://tex.z-dn.net/?f=%5Cfrac%7B%282%2A16%5Cfrac%7Bg%7D%7Bmol%7D%29%7D%7B44.01%5Cfrac%7Bg%7D%7Bmol%7D%20%7D%20%2A100%3D72.7%25)
Therefore C is 27.3 % and O is 72.7 % by mass in 1 mol CO![_{2}](https://tex.z-dn.net/?f=_%7B2%7D)
I think it’s B. I’m not 100% sure but I believe it is B! Srry if this is late btw.
Option three, starfish is the correct answer since if you draw a line between it, it would be even!
