Answer:
= 6.56 × 10²⁴ ions
Explanation:
We are given;
10.9 moles of Iron (iron doesn't exists as a molecules, so we can't have 10.9 molecules but we can have 10.9 moles)
We are required to determine the number of ions
We need to know that;
1 mole of iron = 6.022 × 10²³ ions
Therefore;
10.9 moles of iron will contain;
= 10.9 moles × 6.022 × 10²³ ions/mol
= 6.56 × 10²⁴ ions
Hence, 10.9 moles of iron contains 6.56 × 10²⁴ ions
