Question

What volume of each solution contains 0.25 mol of KCl?

a) 0.355 M KCl solution
b) 0.500 M KCl solution
c) 0.750 M KCl solution
d) 1.00 M KCl solution

Answer 1

To find the volume of KCl solution that contains 0.25 mol KCl, divide the number of moles by the molarity of each solution. The calculated volumes for 0.355 M, 0.500 M, 0.750 M, and 1.00 M solutions are 0.704 L, 0.500 L, 0.333 L, and 0.250 L, respectively.

Step-by-step explanation:

To calculate the volume of each KCl solution that contains 0.25 mol of KCl, we use the formula molarity (M) = moles of solute (mol) / volume of solution (L). We rearrange the formula to solve for volume: volume of solution (L) = moles of solute (mol) / molarity (M). By plugging in the given moles (0.25 mol KCl) and molarities for each solution, we get:

a) Volume = 0.25 mol / 0.355 M = 0.704 L

b) Volume = 0.25 mol / 0.500 M = 0.500 L

c) Volume = 0.25 mol / 0.750 M = 0.333 L

d) Volume = 0.25 mol / 1.00 M = 0.250 L

Thus, we've calculated the volume of each KCl solution that contains 0.25 mol of KCl.
