Assume that the partition coefficient, K, for partitoning of compound A between diethyl ether and water is 3; that is, A preferentially partitions into ether.
A) Given 400 mL of an aqueous solution containing 12g of compound A, how many grams of A could be removed from the solution by a single extraction with 200 mL of diethyl ether?
Compute the number of mol of S represented by 1.810 x 10 -27 atoms of S, also determine the number of atoms of sulfur in 5.22 x 10 -7 kilograms of sulfur.
How many liters of water vapor can be produced if 13.3 liters of methane gas (CH4) are combusted, if all measurements are taken at the same temperature and pressure?

Concrete used in road construction is reinforced using steel bars in a grid, known collectively as "rebar." After many years, rebar will begin to corrode, and the concrete will weaken.
