Calculate the number of vanadium atoms in a 140.0 g sample of vanadium(V) oxide (V205). Be sure your answer has a unit symbol if necessary, and round it to 4 significant digits.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
