Question

calculate the number of atoms in 12 moles of Be​

Answer 1

Answer:

72.264*10²³

Explanation:

1 mole of Be has 6.022*10²³

12 mole of Be has =  6.022*10²³*12

                              = 72.264*10 ²³

Answer 2

How many atoms are in a mole of beryllium?

6.22x1023 atoms

Beryllium (atomic number 4) has a molar mass of 9.012 g/mol. This means that every mole (6.22x1023 atoms of Beryllium) if gathered together on a triple beam balance would have a mass of 9.012g.

How many atoms are in 12 moles?

12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
