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)?

Expert Solution
Step 1

We know that, density is defined as the mass per unit volume. i.e.

                    density = Massvolume

Given, volume of benzene = 1.5 mL

            density of benzene = 0.879 g/mL

            diluted volume of benzene = 100 mL
