HERE IS UR ANSWER

_____________________❤

1L=5.85

1mL=5.85/1000

moles in 1mL are 5.85×10³

Answer 2

Answer:

your ans is 1.2*10^20

Explanation:

Molarity of NaCl=5.8558.5×10−1

∴ 1ml of NaCl=10−4mol

1 mol of NaCl=6.023×1023 molecules of NaCl .But NaCl molecules are dissociated into two ions (Na+ and Cl−)

∴ 1mol of NaCl =6.023×1023×2ions.

∴1×10−4mole of NaCl =6.023×1023×2ions.

⇒1.2×1020ions

Hence 1.2×10^20ions is the correct answer.
