Question

how many moles are there in 4.5 moles of sodium chloride?​

Answer 1

Explanation:

If we have 4.5 moles of sodium chloride (NaCl), then we have 4.5 times Avogadro's number of NaCl molecules.

Avogadro's number (N_A) is 6.022 x 10^23 molecules/mole.

So, the number of molecules of NaCl in 4.5 moles is:

4.5 moles x 6.022 x 10^23 molecules/mole = 2.71 x 10^24 molecules.

Therefore, there are 2.71 x 10^24 molecules (or atoms) of sodium chloride in 4.5 moles of NaCl.
