Question

A commercial available sample of sulphuric acid is 15% H2so4 by weight (density=1.10g/ml) calculate molality normality molarity​

Answer 1

Answer:

Explanation:

A commercial available sample of sulphuric acid is 15% H2so4 by weight (density=1.10g/ml) calculate molality normality molarity​

Therefore,

15% solution of H2So4 mean that 15gm of H2So4 is present in 100gm of solution or 85gm of solvent.

Molarity =Mass of the solution in gm×1000 /Molar mass ×Volume of the solution in ml

=15×1000/98×90.90

=1.68M
