To what volume must 300cm\(^3\) of 0.60M sodium hydroxide solution be diluted to give a 0.40M solution?
A. 450cm\(^3\) B. 300cm\(^3\) C. 200cm\(^3\) D. 150cm\(^3\)
Correct Answer: A
Explanation
From the dilution law  C\(_1\)V\(_1\) = C\(_2\)V\(_2\)  C\(_1\) = Initial Concentration of NaOH = 0.6M  V\(_1\) = Initial Volume of NaOH = 300cm3  C\(_2\) = Final Concentration of NaOH = 0.4M  V\(_2\) = Final Volume of NaOH = ?  V\(_2\) = \(\frac{C_1V_1}{C_2}\)  V\(_2\) = \(\frac{0.6 \times 300}{0.4}\)  V\(_2\) = 450 cm\(^3\) Correct Computation as it follows the equation specified
