Question

Explains the preparation of different
concerated solution
​

Answer 1

Answer:

Also, the number of moles of solute in 258 mL of the stock solution is the same as the number of moles in 2500 mL of the more dilute solution; only the amount of solvent has changed. ... Consequently, the concentration of the solute must decrease by about a factor of 10, as it does (3.00 M → 0.310 M).
