H2SO4 = 2 + 32 + 64 = 98 Mol.mass.
98 ÷ 98 = 1 mole of Sulfuric acid.
HCl = 1 + 35.5 = 36.5 Mol.mass.
0.005 ÷ 36.5 = 0.000137 mole of Hydrochloric acid

The molar mass of sulfuric acid is 98g/mole, so 98g is equivalent to 1 mole of sulfuric acid.
The molar mass of hydrochloric acid is 36.4606g, therefore 0.005g is equivalent to 0.005/36.4606 = 0.000137 moles of HCl.

98g H2SO4 X 1mole/98 g H2SO4 = 1mole
.005g Hcl X 1 mole HCl/35.5 g Hcl = .0014 moles HCl
