Mass of carbon / Mass of acetone x 100% = Percentage by mass Carbon<span>.
</span>Take the formula mass of acetone, <span>and then do the calculation.</span>
The answer is (4) heptane. Saturated hydrocarbon means that there is no double bonds between the carbon atoms. For propene and butene, there is double bond. For ethyne, there is triple bond.
I think its tweezers they pick up anything small
