A mixture containing 80.0 nM iodoacetone (designated A) and 64.0 nM p-dichlorobenzene (designated B) gave the relative detector response (peak area of A)/(peak area of B) = 0.71 in a chromatography experiment. A solution containing an unknown quantity of A plus 930 nM B gave a relative detector response (peak area of A)/(peak area of B) = 1.21. Find the concentration of A in the unknown.
Compute the value of ΔH ° if the combustion products are CO2 (g) and H2O (g). it isgiven that: CO 2 (g) = ΔHf ° - 393.5 kJmol-1; H 2 O (l) = ΔHf ° -285.8 kJmol-1; H 2 O (g) = ΔHf ° -241.8 kJmol -1.
