Answer / explanation:
Number of atoms in 5 moles of silver (Ag)
To solve this problem is just straight forward, since we are given the number of moles already, so we don't need to calculate for number of mole again, only if we are given the number of grams, then we use this formula to calculate of moles
n = m / Mm
n = number of moles
m = number of mass
Mm = number of molar mass
Let's go back to the question
Number of atoms = 5 * 6.023 * 10^23 (avogadro's constant)
= 3.0115 * 10^24 atoms
