to make diluted solutions from concentrated solutions, we can use the following formula,
C1V1 = C2V2
C1 is concentration and V1 is volume of concentrated solution taken to dilute the solution,
C2 is concentration and V2 is volume of diluted solution.
substituting values in the equation,
0.266 M x V = 0.075 M x 150.0 mL
V = 23.6 mL
therefore answer is 23.6 mL
