Did you know that the WHO recommended limit for arsenic in drinking water is equal to 0.000014 grams of arsenite (AsO2-)/ L solution? Given this, I'd like you to determine whether a given solution sample is safe according to the WHO recommendation. In particular, can you tell me how many grams of arsenite (AsO2-) / L solution are in a sample with 0.58 moles of arsenite (AsO2-) in 100 kiloliters (100 kL) of solution? Your result should have 2 significant figures. (Here is a hint to help you: the molecular weight of arsenite (AsO2-) is 106.9 g AsO2- / mol AsO2-)
