The fda limit for levels of toxic methylmercury in fish is 1 ppm. in a 100 g sample of fish, what mass of methylmercury does this equal?

ppm i.e. parts per million is a unit of concentration.

It is mentioned that the FDA limit of methylmercury in fish is 1 ppm

This means that the allowed level is 1 mg of methyl mercury for every 1 kg of the sample of fish

1 ppm = 1 mg/kg

For a 100 g i.e. 0.1 kg sample of fish the allowed levels of methyl mercury would be = 0.1 kg * 1 mg/1 kg = 0.1 mg

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
