A. 450cm³
B. 300cm³
C. 200cm³
D. 150cm³
Correct Answer:
Option A – 450cm³
Explanation
From the dilution law
C1V1 = C2V2
C1 = Initial Concentration of NaOH = 0.6M
V1 = Initial Volume of NaOH = 300cm³
C2 = Final Concentration of NaOH = 0.4M
V2 = Final Volume of NaOH =?
V2 = C1V1/C2
V2 = (0.6×300)/0.4
V2 = 450 cm³
Correct Computation as it follows the equation specified
