Diamond is one form of elemental carbon engagement ring contains a diamond weighing 1.25 carats (1 carat is equal to 200
mg). ? ow many atoms are present in the diamond.

Explanation:

First of all we need to dererminate the diamond mass by transforming carats in grams

Upon consulting a periodic table one finds the atomic mass of carbon

C=12.01 g/mol

Knowing the carbon mass and the avogrado constant (1 mole = ) one compute how many atoms there are in 0.250 g of diamond

i think it's c. i'm not sure but i think so.
