Answer:
Particles? Calcium hydroxide does not exist as discrete molecules, but as a network solid. The only way you would have separate particles, is if the calcium hydroxide was dissolved in a boatload of water. Ca(OH)2 is not all that soluble in water. Nonetheless, assume a lot of water, enough to dissolve 56.9 moles.
Ca(OH)2 --> Ca2+ + 2OH-
56.9 moles Ca(OH)3 x (3 moles ions / 1 mol Ca(OH)2) = 170.7 mol ions
==================
Percent composition of CuNO3......molar mass = 125.5 g/mol
Cu.... 1 x 63.5 / 125.5 x 100 = 50.6% Cu
N ......1 x 14.0 / 125.5 x 100 = 11.2% N
O .....3 x 16.0 / 125.5 x 100 = 38.2% O
