Answer:
4 moles of hydrogen = 2.4092 x 10^24 atoms
Explanation:
Answer:
[Cl⁻] = 0.135 M
Explanation:
The concentration of Cl⁻ is equal to the total moles of Cl⁻ divided by the total volume:
C = n/V
All of the moles of Cl⁻ come from dissociation of the KCl:
KCl ⇒ K⁺ + Cl⁻
We will calculate the moles of Cl⁻ based on the amount of KCl added by using the molar ratio of 1:1.
(0.345 mol/L)(63.0 mL) = (21.735 mmol KCl)(Cl⁻/KCl) = 21.735 mmol Cl⁻
Extra significant figure are kept to avoid round-off errors.
Now we can calculate the total volume, which is the sum of the volume of the three solutions added:
(39.0 mL) + (59.0 mL) + (63.0 mL) = 161.0 mL
Finally, we calculate the concentration of Cl⁻
[Cl⁻] = (21.735 mmol) / (161.0 mL) = 0.135 M
