A dilution of benzene in methanol is made by placing 1.5 mL benzene (density of benzene is 0.879 g/mL and its mol. Wt. is 78.1) in a 100-mL volumetric flask and brining to volume with methanol. Use 3 significant digits throughout What is the concentration of benzene in the solution in mg/L? In ppml (parts per million liquid)?
