Answer:
1.726 NA ions
Explanation:
Na+ has 1 ion
Cl- has 1 ion
total no of ions in a molecule =2
molar mass of NaCl = molar mass of Na + molar mass of Cl
= 23g + 35.5g
= 58.5g
No. of moles in 50.5g=50.5/58.5
No. of ions = 6.022×10²³× no. of moles ×2
= 6.022×10²³× 50.5/58.5×2
= 1.726 NA ions or 10²⁴ ions
