Convert 3.5 x 10^23 k atoms to moles 0.58 moles 2.1 x 10^47 moles 5.8 x 10^45 moles 2.5 x 10^23 moles

We can determine the number of moles using Avogadro's constant, which is defined as 6.02x10^23 atoms/mole. Using stoichiometry so the units (atoms) cancel: 3.5 x 10^23 atoms x (1 mole/6.02x10^23 atoms) = 0.58 moles of K atoms

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other
