Plutonium (atomic mass $=244\,\mathrm{g\,mol^{-1}}$) crystallizes in monoclinic lattice ($\mathrm{a=620\,pm}$, $\mathrm{b=480\,pm}$, $\mathrm{c=1100\,pm}$; $\beta=102^{\circ}$) with 16 atoms per unit cell. The density in $\mathrm{g\,cm^{-3}}$ will be close to (Use $\sin\beta=0.98$; $\sin(\beta/2)=0.78$)
