Assuming an ideal gas, calculate the density in $\mathrm{g/cm^3}$ of propane, $\ce{C3H8}$ at $0.000~^\circ\mathrm{C}$ and $1.000~\mathrm{atm}$. (3 significant figures)

I have figured out that I need this formula: $$\frac{n}{V} = \frac{p}{\mathcal{R}T}$$

I have a total of $44.09562~\mathrm{g/mol}$

I am stuck at this point.

8. (6 points) Assuming an ideal gas, calculate the density in g/cm3 of propane (C3H8) at 0.000 ˚C and 1.000 atm. Please give the answer in g/cm3 and with 3 significant figures.

I have figured out that I need this formula n/v = p/rt -----I have a total of 44.09562 g/mol

I am stuck at this point. Can someone help me?
