Answer to Question #243364 in Chemistry for Boo

Question

How many sodium ions are in 3.0 moles of NaCI?

Answer 1

Solution:

NaCl → Na⁺ + Cl^-

Hence,

n(Na⁺) = n(NaCl) = 3.0 mol

One mole of any substance contains 6.022×10²³ particles.

Hence,

(3.0 mol Na⁺ ions) × (6.022×10²³ Na⁺ ions / 1 mol Na⁺ ions) = 1.8×10²⁴ Na⁺ ions

Answer: 1.8×10²⁴ sodium ions are in 3.0 moles of NaCI.
