Answer to Question #158560 in Chemistry for bella

Question

How many moles are in 3.26 x 10²³ atoms of Pb?

Answer 1

Solution:

One mole of any substance contains 6.022×10²³ atoms/molecules.

Hence,

Moles of Pb = (3.26 x 10²³ Pb atoms) × (1 mol / 6.022×10²³ atoms) = 0.54 mol

Moles of Pb = 0.54 mol

Answer: 0.54 moles are in 3.26 x 10²³ atoms of Pb.
