Question

you want to determine the volume of 2.5 m lithium nitrate solution needed to make 150 ml of a 1.0 m solution. what is m₁ (molarity of the concentrated solution) for this dilution? 2.5 m lino₃ 1.0 m lino₃ 150 ml

Explanation:

Step1: Recall Dilution Terms

In dilution, \( M_1 \) is molarity of concentrated (stock) solution.

Step2: Identify \( M_1 \)

The stock solution is 2.5 M lithium nitrate. So \( M_1 = 2.5 \, M \).

Answer:

\( 2.5 \, M \)
