The World Health Organization (WHO) set the suggested limit for mercury to 2.3 nanomoles of mercury per kilogram of body mass each day [nmolHg/(kgbodyd)]. One brand of canned light tuna has 18.11 micrograms of mercury per serving [gHg/serving ]. The molecular weight of mercury is 200.59 grams per mole [g/mol]. Assume the average adult weighs 180 pound-force [lbf]. How many servings of canned tuna can the average adult consume in one week before reaching the suggested mercury limit?
