2nd last q solution pl

Q. For preparing 0.1 M solution of H2SO4 in one litre, we need H2SO4.

      (A) 9.8 g                                            (B) 4.9 g

      (C) 49.0 g                                          (D) 0.98 g  2nd last q solution pl

Dear student,

Normality is defined as the number of gram equivalents of solvent per unit volume of solvent. Hence normality of a solution is given as

= mass of solutevol. of solvent×equivalent mass of soluteSo H2 SO4 required will be,= 0.1×98.072=4.9gm

Option B is correct.
