Question

What is the hybridisation of carbon atom in diamond and graphite? How many kg of carbon are present in $0.5$ mole of Buckminster fullerene? (Atomic mass of carbon =12)

Answer 1

Hybridization of carbon in diamond is $s{p}^3$

Hybridization of carbon in graphite is $s{p}^2$

$1$ mole of $C_{60}$ fullerene contains $60$ moles of carbon

$0.1$ mole of $C_{60}$ fullerene contains $60$ moles of carbon

Weight of $C$ atoms= Number of moles of carbon $\times$ atomic mass of carbon

$=6\times 12$

$=72gm=0.072kg$

$0.1$ mole of Buckminster fullerene contains $0.072kg$ of carbon.
