Question

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

Answer 1

7.53*10^23 atoms

Step-by-step 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.

`2.5 mol Ag*(1 molCu)/(2molAg) *(6.022*10^(23) atoms)/(mol)`

Your answer should be 7.53*10^23 atoms.
