A) 0.1 N
B) 0.2 N
C) 0.3 N
D) 0.4 N
Correct Answer: B
Solution :
Strength of resulting mixture, \[N=\frac{{{N}_{1}}{{V}_{1}}+{{N}_{2}}{{V}_{2}}+{{N}_{3}}{{V}_{3}}}{{{V}_{1}}+{{V}_{2}}+{{V}_{3}}}\] \[=\frac{60\times \frac{N}{5}+10\times \frac{N}{2}+30\times \frac{N}{10}}{60+10+30}=0.2\,N\]You need to login to perform this action.
