Solution

The correct option is A $1.68 M$
15% (w/w) $H_{2} S O_{4}$ $\Rightarrow 15 g H_{2} S O_{4}$ in 100 g of solution
$\Rightarrow$ 150 g $H_{2} S O_{4}$ in 1000 g solution
$V o l u m e o f t h e s o l u t i o n = \frac{Mass}{density} = \frac{1000}{1.10} = 909 m L Molarity = \frac{Number of moles of Solute}{volume of solution in L}$
$\Rightarrow \frac{150 \times 1000}{98 \times 909} = 1.68 M$
