What will be the molarity of chloroform ...

What will be the molarity of chloroform in the water sample which contains 15 ppm chloroform by mass?

A

`1.25xx10^(-4)` m

B

`2.5xx10^(-4)` m

C

`1.5xx10^(-3)` m

D

`1.25xx10^(-5)`m

Text Solution

Verified by Experts

15 ppm `=(15)/(10^6)xx10^2=1.5xx10^(-3)g`
Molarity of `CHCl_3 " solution " =(1.5xx10^(-3))/(100)xx(1000)/(119.5)`
`=1.25xx10^(-4)`
