How many molecules are contained in a 4.85g sample of dimethylmercury?

Answer 1

1.27X10^22

Answer 2

To find the number of molecules in a sample of dimethylmercury, you need to calculate the number of moles first. The molar mass of dimethylmercury (Hg(CH3)2) is 230.61 g/mol. Then, divide the mass of the sample by the molar mass to get the number of moles. Finally, use Avogadro's number (6.022 x 10^23 molecules/mol) to calculate the number of molecules.
