Calculate the mass percent of sulphuric acid in a solution prepared by dissolving 4g of sulphur trioxide in a 100 - Science - Atoms and Molecules

Question

Calculate the mass percent of sulphuric acid in a solution prepared
by dissolving 4g of sulphur trioxide in a 100 ml sulphuric acid
solution containing 80 mass percent of h2so4 and having a density
of 1 96g/ml(molecular weight of h2so4 =98) Take reaction so3+ h2o =
h2so4

Mitron Subrhmanyam · Answer

Mass of the solution = volume * density = 100 ml * 1 10
g/ml
= 110 gms
So Mass of sulfuric acid: 15% of 110 gms = 16 5 gms

Calculate the mass percent of sulphuric acid in a solution prepared by dissolving 4g of sulphur trioxide in a 100 ml sulphuric acid solution containing 80 mass percent of h2so4 and having a density of 1.96g/ml(molecular weight of h2so4 =98) Take reaction so3+ h2o = h2so4
