To \(50 \mathrm{~mL}\) of \(0.1 \mathrm{~N} \mathrm{Na}_2 \mathrm{CO}_3\) solution \(150 \mathrm{~mL}\) of water is added. What is the molarity of resultant solution?
- A \(\frac{M}{40}\)
- B \(\frac{M}{20}\)
- C \(\frac{M}{80}\)
- D \(\frac{M}{30}\)
Answer & Solution
Correct Answer
(C) \(\frac{M}{80}\)
Step-by-step Solution
Detailed explanation
\(\because\) Initial volume \(\left(V_1\right)=50 \mathrm{~mL}\) Initial normality \(\left(N_1\right)=0.1 \mathrm{~N}\) Final volume \(\left(V_2\right)=50+150=200 \mathrm{~mL}\) Final normality \(\left(N_2\right)=\) To find and,…
