Approx. 1xx10^22*"carbon atoms".

Explanation:

We got 5.85*g of CBr_4.

This represents a molar quantity of .................

(5.85*g)/(331.63*g*mol^-1)=0.0176*mol

And of course in such a molar quantity, there are 4xx0.0176*mol of bromine, and 1xx0.0176*mol of carbon. Are you with me?

And so we take the product of the molar quantity and Avogadro's number, to get.......

0.0176*molxx6.022xx10^23*mol^-1=1.06xx10^22 individual carbon atoms.....
