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 $^3$

View answer & explanation

Correct answer is A

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
