Question

If 100 mL of 10 M NaOH solution is diluted to 1.0 L,the resulting solution contains

• A. 1 mole of NaOH
• B. 0.1 mole of NaOH
• C. 10.0 mole of NaOH
• D. 0.05 mole of NaOH

Answer 1

Answer: (B)

0.1 mole of NaOH

Answer 2

No. of moles = $\frac{(100 \, mL) \times (1 \, mol \, L^{-1})}{(1000 \, mL \,L^{-1})}$ = 0.1 mol $\therefore$ the given solution contains NaOH = 0.1 mol
