Answer:
Explanation:
From the question we are told that
mass of sample
volume of water
volume for extraction
partition (distribution) coefficient water
initial extraction removal
Generally the equation for the weight of sample is mathematically given by
Generally the weight extracted is therefore
is extracted with 60ml solvent .
Therefore volume of solvent (y) that would be necessary to remove an additional 7.0g
The tool used to measure pressure is a Barometer and is measured in Milibars.
