1. In a research, it has been found that millions of bottled mineral water contain benzene (C6H6) at molarity levels higher than concentrations considered lethal for rats. A sample of a 250 mL mineral water has a concentration of 0.000151 M.
What is the mole of benzene in the sample? (MOLAR MASS OF BENZENE: 78g/mol)
