191.85 g of 10% oleum was mixed with 1 liter of H2SO4 solution with a concentration of 2 mol/dm3 and d=1.1243 g/cm3. One quarter of the solution was used to dissolve 16.345 g of zinc.
Calculate:
a) amount of released hydrogen (in g and dm3)
b) the volume (dm3) of a 1-molar NaOH solution necessary to neutralize the excess H2SO4 after dissolving the zinc.
