It’s a polyatomic and it has a negative charge. It’s located in the nucleus of the atom, along with the protons.
Electrons, everything is pretty much based around the likeliness of electrons to be swapped or shared between atoms
Because they are different they all show different traits
In the problem, we are tasked to solved for the amount of carbon (C) in the acetone having a molecular formula of C 3 H 6 O. We need to find first the molecular weight if Carbon (C), Hydrogen (H), Oxygen (O).
Molecular Weight:
C=12 g/mol
H=1 g/mol
O=16 g/mol
To calculate for the percent by mass of acetone, we assume 1 mol of acetone.
%C=

%C=62.07%
Therefore, the percent by mass of carbon in acetone is 62.07%
