Hey there!
There are 6.022 x 10²³ particles in 1 mole.
We have 3.55 moles.
6.022 x 10²³ x 3.55
2.14 x 10²⁴
This is how many particles we have.
NaCl has 2 atoms for every unit.
So we multiply this by 2.
2 x 2.14 x 10²⁴ = 4.28 x 10²⁴
There are 4.28 x 10²⁴ atoms in 3.55 moles of sodium chloride.
Hope this helps!
Answer:
We know that 1 mole of anything contains an Avogadro's number of atoms or 6.023 x 10^23 atoms. Thus, 1 mole of NaCl will contain 6.023 x 10^23 atoms each of Na and Cl, or a total of 12.046 x 10^23 atoms. NaCl is an ionic compound formed by the loss of one electron from Na and the gain of the one electron by Cl.
