How many atoms of hydrogen are in 25kg of calcium hydroxide? Show all calculations.

Answer 1

mols Ca(OH)2 = grams/molar mass = 25,000/about 74 = approx 400. You need to recalculate ALL of these numbers. Mine are simply estimates.
400 mols Ca(OH)2 x (2 mols H atoms/1 mol Ca(OH)2 = approx 800 mols H
atoms. Then there are 6.02E23 atoms in a mol
Post your work if you get stuck
