Question

What volume of a 2.5 M NaOH solution is required to prepare 2.0 liters of a 0.75M NaOH? A. 2.5 liters B. 6.7 liters C. 0.60 liter D. 1.0 liters E. 0.75 liter

Answer 1

C. 0.60

Step-by-step explanation:

Mi x Vi = Mf x Vf

2.5 x Vi = 0.75 x 2.0

2.5 x Vi = 1.5

Vi = 1.5 / 2.5

Vi = 0.6 L
