Borospherene is a cage-like cluster molecule with the chemical formula B40\text{B}_{40}B40​.

Calculate the number of B40\text{B}_{40}B40​ molecules that can be formed from 0.180.180.18 moles of pure boron atoms.

Give your answer in standard scientific form to two significant figures.

The Avogadro constant =6.02×1023 per mole= 6.02 \times 10^{23}\text{ per mole}=6.02×1023 per mole.
