I don’t think we are supposed to be able to determine molecular formula based off given structures so I’m sure if you look it up, which is what I did, that it would be fine until we learn how to determine formulas from structures given!
I know we haven't gone over it, but the picture showed the molecular formula. Each corner represents a carbon. There were 4 carbons, so you could redraw it as a lewis structure and go from there. I checked online as well!
I get what you mean. This problem actually has implications of organic chemistry. The lines represent covalent single bonds between carbon and hydrogen. So if you were to draw the model and add the double covalent bonds of the O for the 2-butanone you could actually add up the molar masses for each element that way and calculate the total molecular mass. But that seemed a bit much so I just looked it up online. It is just another way to look at it.
Thank you to those who said just to look it up. I was staring at those bonds for like twenty minutes trying to understand what was going on. This helped me extremely, and now I am looking forward to learning organic chemistry.
