Ihave always enjoyed eating tuna fish. unfortunately, a study of the mercury content of canned tuna in 2010 foundthat chunk white tuna contains 0.6 ppm hg and chunk lighttuna contains 0.14 ppm. (s. l. gerstenberger, a. martinson, and j. l. kramer, environ. toxicol. chem. 2010, 29, 237.) theu. s. environmental protection agency recommends no morethan 0.1 mg hg/kg body weight per day. i weigh 68 kg. howoften may i eat a can containing 6 ounces (1 lb 5 16 oz) ofchunk white tuna so that i do not average more than 0.1 mghg/kg body weight per day? if i switch to chunk light tuna, how often may i eat one can?

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
