A 72.0 g sample of an organic solid is dissolved in 180mL of water. The solid is extracted using one 60 mL extraction in the first extraction of an organic solvent which has a partition (distribution) coefficient with water of 10. The first extraction removed 55.4 g of solid from water. What are the numbers that need to go in box A and B to calculate the volume of solvent (y) that would be necessary to remove an additional 7.0g from the remaining sample dissolved in water. You DON'T have to complete the calculation to solve for y.

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

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
