Question

The number of molecules in 100 ml of 0.02N of h2so4

Answer 1

H2SO4 → SO42- + 2H+
Since one mole of H2SO4 = 2 moles equivalents of H+
Therefore, molarity = normality/2
= 0.01 M
Now, 0.01M = 001noofmolesofH2SO41000Volumeofsolutioninml
Or

We know that
No of molecules in one mole = 6.0221023
Therefore, no of molecules in 0.001 mol = 0.001​6.022​1023, i.e 0.006 ​1023molecules.
