Answer to Question #154348 in General Chemistry for mischa

Question

how many moles are there in 2.30 x10^24 atoms of silver

Answer 1

Solution:

The Avogadro constant N_A= 6.02×10²³ units in one mole of any substance. The units may be electrons, atoms, ions, or molecules.

The number of particles of a substance can be calculated using the Avogadro constant N_A, the amount of substance in mole n.

Number of particles N = Avogadro constant N_A × amount n

Therefore,

n = 2.30×10²⁴ / 6.02×10²³ = 3.82 mol

Answer: there are 3.82 moles of Ag.
