Question
0.1 mole of Buckminster fullerene contains how many kg of carbon? [Atomic mass of carbon = 12]
Solution
1 mole of C60 contains 60 moles of C.
0.1 mole of C60 will contain 6.0 moles of C.
Weight of C-atoms = Number of moles of C x atomic mass of C
= 6.0 x 12
= 72.0 g
= 0.072 kg
0.1 mole of Buckminster fullerene contains 0.072 kg of carbon.
