Homework Equations
The Attempt at a Solution
I'm having trouble with this question, I am not getting a whole number value for mass so I don't know what to do.
I did this: 3C->36g , 2H -> 2g , O -> 16 g, TOTAL: 54g
Compound: 192.8.
192.8/54 = 3.57.
Therefore, I guess it could be a or b as an answer, but I don't know what to do. Can someone help?
