Question

How many atoms of beryllium are equal to 0.39 moles of beryllium?

Answer 1

2.35 x 10²³atoms

Step-by-step explanation:

Given parameters:

Number of moles of Be = 0.39moles

Unknown:

Number of atoms = ?

Solution:

To solve this problem:

1 mole of a substance contains 6.02 x 10²³ atoms

0.39 mole of Be will contain 0.39 x 6.02 x 10²³ = 2.35 x 10²³atoms
