Answer 1

Answer:

12.044 × 10^23

Explanation:

Avagadro's no. is the no. of atoms/molecules present in 1mole of any element/compound.

It is 6.022×10^23.

Now,

No. of moles if Na=2

No. of atoms of Na=2×6.022×10^23

=12.044×10^23

Answer 2

Hello!

Here is the answer for your question!

Question:- What is the number of atoms in 2 moles of Sodium ?

------------------------------------------------------------------

Answer:-

• 1 mole of any substance contains 6.02 × 10^23 atoms (which is avogardo's number)

so, 1 mole of sodium contains 6.02 × 10^23 atoms

• 2 mole of sodium contains

2× 6.02 × 10^23 number of atoms

• which is 12.04 × 10^23

so, 2 moles of sodium contain 1.20 × 10^24 atoms
