How many Fe(II)ions are there in 10.0 g of FeSO₄? A) 1.93 × 10^-²⁵ iron(II) ions B) 3.96 × 10²² iron(II) ions C) 9.15 × 10²⁴ iron(II) ions D) 9.14 × 10²⁶ iron(II) ions

Question

Quizplus · Accepted Answer

To find the number of Fe(II) ions in 10.0 g of FeSO₄, first calculate the molar mass of FeSO₄, which is approximately 151.9 g/mol. Then, divide 10.0 g by the molar mass to find the number of moles of FeSO₄. Multiply the number of moles by Avogadro's number (6.022 × 10²³) to find the number of Fe(II) ions. This calculation results in approximately 3.96 × 10²² Fe(II) ions.
