5. How many Ca2+ ions are present in 1.00 mol of Ca(OH)2? 6. How many OH– ions are present in 1.00 mol of Ca(OH)2? 7. How many OH– ions are present in 4.00 mol of Ca(OH)2?

Answer 1

5). 1.00 mol Ca(OH)₂ x 1 mol Ca²⁺ / mol Ca(OH)₂ = 1.00 mol Ca²⁺

6). 1.00 mol Ca(OH)₂ x 2 mol OH- / mol Ca(OH)₂ = 2.00 mol OH-

7). 4.00 mol Ca(OH)₂ x 2 mol OH- / mol Ca(OH)₂ = 8.00 mol OH-
