If Avogadro number N A , is changed from 6.022 × 10 23 m o l - 1 to 6.022 × 10 20 m o l - 1 , this would…

If Avogadro number NA , is changed from 6.022×1023 mol-1 to 6.022×1020 mol-1 , this would change:
  1. The definition of mass in units of grams
  2. The mass of one mole of carbon
  3. The ratio of chemical species to each other in a balanced equation.
  4. The ratio of elements to each other in a compound.

Solution

Mass of 1 mol (6.022×1023 atoms) of carbon = 12g
If Avogadro Number (NA) is changed then mass of 1 mol (6.022×1020 atom) of carbon
=12×6.022×10206.022×1023=12×10-3 g
