How to find concentration of the solutions
Asked by fathimafero | 11 Sep, 2019, 14:00: PM
Concentration is expressed in various concentration terms.
Basic formulae of concentraion is:
![C o n c e n t r a t i o n equals fraction numerator A m o u n t space o f space s o l u t e over denominator A m o u n t space o f space s o l v e n t end fraction
space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space space o r
C o n c e n t r a t i o n equals fraction numerator A m o u n t space o f space s o l u t e over denominator A m o u n t space o f space s o l u t i o n end fraction](https://images.topperlearning.com/topper/tinymce/cache/7f92a69f6ef03b21fb8bc31d3bf99a07.png)
There are two major ways of expressing concentration-
![left parenthesis 1 right parenthesis space M a s s space b y space m a s s space p e r c e n t a g e space o f space a space s o l u t i o n equals fraction numerator M a s s space o f space s o l u t e over denominator M a s s space o f space s o l u t i o n end fraction cross times 100
left parenthesis 2 right parenthesis thin space M a s s space b y space v o l u m e space p e r c e n t a g e space o f space a space s o l u t i o n equals fraction numerator M a s s space o f space s o l u t e over denominator v o l u m e space o f space s o l u t i o n end fraction cross times 100](https://images.topperlearning.com/topper/tinymce/cache/07b17c7300bbdcefddeb8a116d98c8eb.png)
