Answer:

The carat represents a mass of #0.200*g#, and is a measure commonly used for gemstones.

Explanation:

So, #"moles of carbon"# #=# #(26" carat"xx0.200*g*"carat"^-1)/(12.011*g*mol^-1)#.

We mutliply this molar quantity by #"Avogadro's number ", 6.022xx10^23*mol^-1#, to give the number of carbon atoms.
