A) 0.01 M
B) 0.001 M
C) 0.05 M
D) 0.002 M
Correct Answer: D
Solution :
Molarity of \[N{{a}_{2}}C{{O}_{3}}\] solution \[=\frac{2.65}{0.6}\times \frac{1000}{250}=0.1M\] 10 mL of this solution is diluted to 500 mL \[{{M}_{1}}{{V}_{1}}={{M}_{2}}{{V}_{2}}\] \[0.1\times 10={{M}_{2}}\times 500\Rightarrow {{M}_{2}}=0.002M\]
