Using Formula Weights
Alkyl derivatives of mercury are highly toxic and can cause mercury poisoning in humans. Dimethylmercury is one of the strongest known neurotoxins. Although it is said to have a slightly sweet smell, inhaling enough to discern this would be hazardous.
Give the empirical formula of dimethylmercury.
How many molecules are contained in a 6.05-g sample of dimethylmercury?
What is the percentage of mercury (by mass) in the sample?
