How many atoms of solid copper will be formed if you start with 2.5 moles of silver, based off the reaction: 2Ag + Cu(NO₃)₂ → Cu + 2AgNO₃

7.53*10^23 atoms

Explanation:

Using stoichiometry convert moles of silver to moles of copper.  Based on the equation, for every 2 moles of silver, 1 mole of copper is produced.

Then, convert moles to atoms with Avogadro's number.

Your answer should be 7.53*10^23 atoms.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
