Answer:
1.004×10²²
Explanation:
The molar mass of carbon is 12 g/mol
which means that:
1 mole of carbon atoms has a mass of 12 grams.
Since, diamond is a allotrope of carbon.
Mass of 1.00-carat diamond in grams is:
1.00 carat = 0.200 g
Since, 1 mole of C contains 6.022×10²³ atoms of C
So,
12 grams contains 6.022×10²³ atoms of C
1 gram contains 6.022×10²³/ 12 atoms of C
0.200 gram contains (6.022×10²³/ 12)×0.200 atoms of C
Thus,
1 carat diamond contains 1.004×10²² atoms of C.
