There is a shortcut to this Chem question. simply look at this problem as if it were a cooking recipe. you have 7 parts Carbon and 18 Parts Hydrogen for a total of 25 parts. Simply divide 5.2 by 25 then multiply by 7 to get your answer.
(5.2/ 25) 7 = 1.456 moles
The equilibrium constant<span> of a chemical reaction is the value of the reaction quotient when the reaction has reached </span>equilibrium<span>. An </span>equilibrium constant<span> value is independent of the analytical concentrations of the reactant and product species in a mixture, but depends on temperature and on ionic strength.</span>
The answer is that all of them are correct.
