Answer:

3.76 × 10²³ atoms

Explanation:

1 mole = 6.022 × 10²³ atoms (Avogadro's number)

Therefore, 0.625 moles of Ge will have:

Multiply the given moles by number of atoms per mole.

= 0.625 moles ×6.022 × 10²³ atoms/mol

= 3.76 × 10²³ atoms

Iron(II) sulfide reacts with hydrochloric acid according to the reaction:
Inessa [10]
The balanced chemical reaction would be:

FeS(s)+2HCl(aq)→FeCl2(s)+H2S(g) 

We are given the amount of the reactants to be used for the reaction. We use these amounts. First, we determine the limiting reactant of the reaction. From the data, we can say that FeS is the limiting ad HCl is the excess reactant. We calculate as follows:

Amount of HCl used: 0.240 mol FeS x 2 mol HCl / 1 mol FeS = 0.48 mol HCl

0.646 - 0.48 = 0.166 mol HCl left
