Solution

The correct option is D 200 mL of $0.2 M H C l O_{4}$
The number of moles would give us the maximum number of molecules $= M \times V$ , lets do this with the volume in litres:
$H C l = 0.1 \times 0.1 = 0.01$
$H_{2} S O_{4} = 0.5 \times 0.05 = 0.025$
$H N O_{3} = 2 \times 0.01 = 0.02$
$H C l O_{4} = 0.2 \times 0.2 = 0.04$
