Answer:

There is 1,00 mol of #"NaCl"#.

Explanation:

#M_text(r) ("NaCl") = A_text(r) ("Na") + A_text(r) ("Cl") = "23 + 35,5" = "58,5"#

So, 1 mol of NaCl has a mass of 58,5 g.

#"Moles of NaCl" = "58,5" color(red)(cancel(color(black)("g NaCl"))) × "1 mol NaCl"/("58,5" color(red)(cancel(color(black)("g NaCl")))) = "1,00 mol NaCl"#
