Question

The mercury content of a certain fish species was determined by atomic absorption spectroscopy. The sample data are:
Mass of fish(g) 18.6
Final sample volume(mL) 25.0
Absorbance (mean) 0.280
Oliver loves eating fish, especially before a big soccer game to give him that little bit of extra energy. However, he wants to avoid eating fish with a concentration greater than 0.5mg/kg of fish. Calculate the concentration of mercury in the fish sample he tested and state whether he should eat it.

Answer 1

0.28 x 1000/18.6 x 25 = 0.6.

0.5<0.6

He should not eat
