Question

Find the mass of h2so4 present in 100cm3 of a decimolar solution

Answer 1

molecular mass of H2SO4 = 98 g

malarity = no of moles of H2SO4/Volume of solutions in l

1/10 = no of moles ×1000 / 100

no of moles = 0.01

mass fof H2SO4 in solutions = no of moles ,× molecular mass

= 0.01 ×98

= 0.98 g
