# What volume does 4.05 mol C_6H_12O_6 occupy at STP?

I doubt that a compound with formula ${C}_{6} {H}_{12} {O}_{6}$ is gas as STP. It should be a solid or a liquid.
Its molecular mass is 180.15 g/mol. If we considere it is glucose the density will be $0.909 \frac{g}{c {m}^{3}}$
So the volume will be $4.05 \times \frac{180.15}{0.909} = 803 c {m}^{3}$.
