Question:

How many moles of silver (Ag) are present in a sample of 3.8 x 1024 atoms Ag?

a) 1.6 mol Ag

b) 2.3 mol Ag

c) 6.3 mol Ag

d) 22.8 mol Ag

ANSWER: C

1 mol=6.022 x 10²³ atoms.

1 mol—————————–6.022 * 10²³ atoms
x——————————–3.8 * 10²⁴ atoms

x=(1 mol * 3.8 * 10²⁴ atoms) / 6.022*10²³ atoms=6.3 moles of Ag,

Avogadro’s Number:

Avogadro’s number quantifies the quantity of elementary particles that are contained in one mole of a substance. Its value is absolute, meaning it is constant for any type of compound and form of particle.
