Let's use stoichiometry!

It's easier to think about if you focus on one relationship at a time.

$1.0 \cdot {10}^{25} \text{molecules" * "mol"/(6.02*10^23"molecules") * (154"g")/(C Cl_4) * ("cm"^3)/(1.5"g") * "mL"/"cm"^3 * "L"/(10^3"mL") approx 1.7"L}$

of one molar carbon tetrachloride solution must be measured out to "contain" that many molecules, given your data.
