Parts per million?
Posted: Fri May 13, 2016 3:26 am
A 40l sample of gas containing gas as an impurity was bubbled through a 3% solution of . The was converted to :
A 25ml portion of 0.0100mol/l was added to the solution, and the excess base was back-titrated with 13.6ml of 0.0100mol/l . Calculate the parts per million of (that is ml /10^6ml sample) if the density of is 2.85g/l (Atomic weights: H=1, N=14, O=16, Na=23, S=32, Cl=35.5).
Please explain. I have never solved chemical problems of this kind.
