450 mL
Explanation:
First we calculate how many NaCl moles would there be in 1.5 L of a 0.75 M solution, using the definition of molarity:
Molarity = moles / LitersMoles = Molarity * LitersMoles = 1.5 L * 0.75 M =1.125 molOnce again using the definition of molarity, we now calculate how many liters of a 2.5 M solution would have 1.125 moles:
Liters = 1.125 mol / 2.5 M = 0.45 LFinally we convert 0.45 liters to mL:
0.45 L * 1000 = 450 mL
