To what volume must 300cm(^3) of 0.60M sodium hydroxide solution be diluted to give a 0.40M solution?

Correct Answer: Option 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
