Answer:
Copper(II) nitrate and potassium hydroxide are soluble ionic compounds, which implies that they dissociate completely when dissolved in water to produce ions. ... You can thus say that the balanced chemical equation that describes this double ... Cu(NO3)2(aq)+2KOH(aq)→Cu(OH)2(s)⏐⏐↓+2KNO3(aq).
Number of atoms = mole x Avogadro’s Number
= 0.1 x 6.022 x 10^23
= 6.022 x 10^22
