I think the answer would be trenches but I’m sorry if I’m wrong
Hello there!
<span> Use Avogadro's number, 1 mol = 6.02 x 10^23 atoms.
</span>Convert atoms to moles and you get:
<span>9.97x10^(-15) moles Co

Hope This Helps You!
Good Luck :)

Answer:</h3>
0.35 M
<h3>
Explanation:</h3>
<u>We are given;</u>
- Initial volume as 35.0 mL or 0.035 L
- Initial molarity as 12.0 M
- Final volume is 1.20 L
We are required to determine the final molarity of the solution;
- Dilution involves adding solvent to a solution to make it more dilute which reduces the concentration and increases the solvent while maintaining solute constant.
- Using dilution formula we can determine the final molarity.
M1V1 = M2V2
M2 = M1V1 ÷ V2
= (12.0 M × 0.035 L) ÷ 1.2 L
= 0.35 M
Thus, the final concentration of the solution is 0.35 M
Na3P is the formula if that helps
