Avogadro’s number = 6.022 x 1023 entities
entities = atoms, ions, molecules, particles, formula units
Assuming total mass = 100 g then: % element = mass element
Solving for atoms of each element except others:
= 6.022 x 1023 H atoms
= 2.44 x 1024 O atoms
= 9.033 x 1023 O atoms
Use formula for each element:
% atom H = ~ 15.3 % > 10%
% atom O = ~ 61.8 %
# atom C = ~ 22.9 %
If the lower pie chart was drawn as the percentage in terms of number of atoms rather than the percentage in terms of mass, would the hydrogen slice of the pie get larger or smaller?
