Solutions Question 150
Question: The molarity of a solution made by mixing 50ml of conc. $ H_2SO_4 $ (36N) with 50 ml of water is [MP PMT 2001]
Options:
A) 36 M
B) 18 M
C) 9 M
D) 6 M
Show Answer
Answer:
Correct Answer: C
Solution:
$ N_1V_1=N_2V_2 $ , $ 36\times 50=N_2\times 100 $
$ N_2=\frac{36\times 50}{100}=18 $ ; $ 18NH_2SO_4=9M,H_2SO_4 $ .
