A solution of sulfuric acid has a concentration of 0.0980 g/L. If the density of the acid is 1.84 g/mL, what is the concentration in ppm

Solutions

Expert Solution

mass = volume* density

let volume of solution is 1000ml

mass of solution = volume of solution * density of solution

                         = 1000*1.84   = 1840gm of solution

mass of sulphuric acid = volume of sulphuric acid in L * density of sulphuric acid in g/L

                                  = 1L * 0.0980

                                  = 0.0980gm of sulphuric acid

weight of solvent = weight of solution - weight of solute

                          = 1840-0.098 = 1839.902 gm

molality = weight of substance* 1000/gram molecular mass *weight of solvent

           = 0.0980*1000/98*1839.902 = 543*106 = 543ppm>>>> answer
