Diamond is 100% pure elemental carbon, compressed to its crystal form, under extreme heat and pressure deep within the Earth. The symbol for carbon is C.
Step-1: convert carat to grams
The carat represent the unit of weight for diamonds and other gemstones. From several sources, it is known that 1-carat = 0.2 grams of carbon atoms.
Converting 1.3-carat to several grams of carbon atoms
So 1.3-carat diamonds are equal to 0.26 grams of carbon atoms.
Step-2: convert grams to moles
From the periodic table of elements, we know that the atomic mass of carbon is 12 g/mol. The relationship between mole, gram, and atomic mass is
Converting 0.26 grams to moles
We obtain 0.0217 moles of carbon atoms.
Final step: convert mole to atoms
The relationship between mole, the number of atoms (N), and Avogadro’s number is
Rounding to 2 decimal places to produce and in the form of scientific notation is
So there is are there in a 1.3-carat diamond.
