Question

what is the volume of a 0.40 m nai solution that contains 0.20 moles nai in it?
m = \frac{mol}{l}
? l

Explanation:

Step1: Recall the molarity formula

The formula for molarity \( M \) is \( M = \frac{\text{mol}}{L} \), where \( M \) is molarity, \( \text{mol} \) is moles of solute, and \( L \) is volume in liters. We need to solve for \( L \), so rearrange the formula: \( L = \frac{\text{mol}}{M} \).

Step2: Substitute the given values

We know \( \text{mol} = 0.20 \) mol and \( M = 0.40 \) M. Substitute these into the rearranged formula: \( L = \frac{0.20\ \text{mol}}{0.40\ \text{M}} \).

Step3: Calculate the volume

Dividing \( 0.20 \) by \( 0.40 \) gives \( L = 0.50 \) L.

Answer:

\( 0.50 \) L
