1. Avogadro's Number
* Avogadro's number tells us the number of particles (atoms, molecules, etc.) in one mole of a substance. It's approximately 6.022 x 10^23 particles/mole.
2. Calculation
* Step 1: Divide the number of molecules by Avogadro's number:
(2.0 x 10^25 molecules) / (6.022 x 10^23 molecules/mole) = 33.2 moles
Answer: There are approximately 33.2 moles of silver nitrate in 2.0 x 10^25 molecules.
