Diamond is a natural form of carbon.
(a) How many moles of carbon are in a 1.25-carat diamond ( 1-carat = 0.200 g)?
(b) How many atoms are in this diamond?
The strings:
S7P1A15 (containership - mass).
The math:
Pj Problem of Interest is of type containership (mass).
(a) Molar mass of carbon = 12
1.25-carat = 1.25(0.200) = 0.25 g
So, moles of 0.25 g of diamond = 0.25/12 = 0.0208 mol of diamond.
(b) 1 mole contains the Avogadro number of atoms = 6.02 x 1023 atoms
So, 0.0208 mol will contain 0.0208 x 6.02 x 1023 = 0.125 x 1023 =1.25 x 1022 atoms.
The point . is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.
