12. Hydrocarbon mixtures are used as fuels. (State the atomic mass of each atom you are using for each solution) How many grams of CO:(g) are produced by the combustion of 200. g of a mixture that is 25.0% CH, and 75.0% Catt, by mass? 13. Nitrogen (N), phosphorus (P), and potassium (K) are the main nutrients in plant fertilizers. By industry convention, the numbers on a label refer to the mass percent of N, P;O, and K0, in that order. (State the atomic mass of each atom you are using for each solution) Calculate the N/P/K ratio of a 30/10/10 fertilizer in terms of moles of each element, and express it as x/y/1.0.
