Question

A. Write Ca(MnO4)2 as a conversion factor.

b. Convert 7.78 x 10^25 atoms of Sodium Sulfate to moles

Answer 1

To convert 7.78 x 10^25 atoms of Sodium Sulfate to moles, we need to use the conversion factor based on Avogadro's number, which tells us that 1 mole of any substance contains 6.022 x 10^23 atoms.

Step-by-step explanation:

To convert 7.78 x 10^25 atoms of Sodium Sulfate to moles, we need to use the conversion factor that relates the number of atoms to the number of moles. The conversion factor is based on Avogadro's number, which tells us that 1 mole of any substance contains 6.022 x 10^23 atoms.

So, we can set up the conversion factor as follows:

7.78 x 10^25 atoms of Na2SO4 x (1 mole Na2SO4 / 6.022 x 10^23 atoms Na2SO4) = 12.9 moles of Na2SO4
