A vessel of volume `V_(0)` is completely filled with a salt solution having specific gravity `sigma_(0)`. Pure water is slowly added drop by drop to the container and the solution is allowed to overflow.
(a) Find the specific gravity of the diluted solution in the contaienr when a volume V of pure water has been added to it.
(b) If `sigma_(0)=1.2` then find the specific gravity of the solution in the container after a volume `V_(0)` of pure water has been added to it.
(c) Plot the variation of `sigma` with V.

Answer

(a) `sigma=1+(sigam_(0)-1)e^(-v//v_(0))`
(b) 1.074
(c) `(##IJA_PHY_V01_C08_E01_073_A01##)`
