Question

if one mole of sodium atom weighs 23 g what is the mass of one atom of sodium​

Answer 1

1M Na= 23g
We know that 1M contains 6.022*10^2 atoms or Avogadro's Number

So mass of 1M = 23g
6.022*10^23 atoms= 23g
So 1 atom= 23/6.022*10^23g

I hope you can calculate it
Hope it helps

Answer 2

Answer:

3.81932912653 x 10^-23 grams

Explanation:

- the 1 mole of any atom contains = 6.022 x 10^23

- Mass of 1 mole of Sodium = 23 g

- mass of 1 Atom = 23/(6.022 x 10^23)

= 3.81932912653 x 10^-23 grams

hope this helps you! Have an amazing day :)
