6.022 x 10^23 molecules in 1.000e+0 mol

  • Your sample contains 6.022 x 10^23 molecules.
  • That equals 1.000e+0 moles of substance.
  • Avogadro's constant ties the macroscopic world (grams, liters) to the atomic world (individual molecules). One mole always contains exactly 6.02214076 x 10^23 entities, regardless of the substance.

Next stepTo find the volume this sample occupies, pair it with a density or ideal-gas-law calculator.
