Recall,

$N = \frac{1 g}{L}$ $"N" = (1"g")/"L"$

Note: this is seen less often outside of laboratories.

Hence, there are,

$10 mL \cdot \frac{L}{10^{3} mL} \cdot \frac{0.1 g}{L} \cdot \frac{mol}{36.5 g} \cdot \frac{6.02 \cdot 10^{23} molecules}{mol} \approx 1.7 \cdot 10^{19} molecules$ $10"mL" * "L"/(10^3"mL") * (0.1"g")/"L" * ("mol")/(36.5"g") * (6.02*10^23"molecules")/"mol" approx 1.7*10^19"molecules"$

of hydrochloric acid present in that small volume of $0.1 N$ $0.1"N"$ solution.
