Question

$0.1mole$ of Buckminster fullerene contains how many kg of carbon?
[Atomic mass of carbon $=12$].

Answer 1

Buckminister fullerene is an allotrope of carbon it was discovered collectively by three scientiss namely $K.E.Smalley$, $R.F.Curl$, and $H.W.Kroto$. All the carbon atoms are equivalent and they undergo $s{p}^2$ hybridization. The formula of Buckminister fullerene is $C_{60}$ Therefore, it's atomic mass is $M=12\times 60=720gmo{l}^{-1}$

Now, no. of moles= $\frac{mass}{molecularmass}$

Therefore, the mass of the substance=$0.1\times 720$$=72g$
