Question: Molarity of liquid $ HCl $ with density equal to $ 1.17g/cc $ is [CBSE PMT 2001]
Options:
A) 36.5
B) 18.25
C) 32.05
D) 4.65
Show Answer
Answer:
Correct Answer: C
Solution:
Molarity = mole/litre $ \because $ 1cc contains 1.17gm
$ \therefore $ 1000cc contains 1170gm $ \frac{1170gm}{Mol\text{.},wt\text{.}} $ $ =\frac{1170}{36.5}=32.05mole/litre $ (Mol. wt. of HCl=36.5)
