(C) First,calculate the molarity $(M_1)$ of the concentrated acid: $M_1 = \frac{\text{density} \times 10 \times \% \text{ by mass}}{\text{molar mass}} = \frac{1.80 \times 10 \times 98}{98} = 18 \ M$. Now,use the dilution formula $M_1 V_1 = M_2 V_2$: $18 \times V_1 = 0.1 \times 1000 \ mL$. $V_1 = \frac{100}{18} \approx 5.55 \ mL$.
