Multiply the number of molecules by the number of molecules per mole for that particular element or molecule (sum of the molecules/mole of each element in the molecule). The number of molecules per mole for any element can be found on charts and on the Periodic Table.

How many molecules are in 4.3 moles of K2SO4?
To calculate the number of molecules in a given number of moles, we use Avogadro's number, which is approximately 6.022 x 10^23 molecules per mole. Therefore, 4.3 moles of K2SO4 would contain approximately 4.3 x (6.022 x 10^23) molecules, which is approximately 2.59 x 10^24 molecules.
How many molecules are in 10.0 g of pure C8H8O3?
To determine the number of molecules in 10.0 g of C8H8O3, we need to calculate the number of moles first. The molar mass of C8H8O3 is 152.15 g/mol. By dividing 10.0 g by the molar mass, we find that there are approximately 0.0658 moles of C8H8O3. To convert moles to molecules, we multiply the number of moles by Avogadro's number, 6.022 x 10^23, giving us about 3.96 x 10^22 molecules.
