The mass % of hydrogen ( H ) in ammonium bicarbonate is to be calculated. Concept introduction: Molar mass is defined as the mass of 1 mol of a chemical substance in grams. The molar mass of a compound is calculated by the addition of the molar mass of each element multiplied by its number of atoms present in the chemical formula. The molecular formula of a compound tells the number of atoms of each element present in the compound. Mass percent of an element represents the concentration of that element in a compound. The molar mass and the formula of the compound are used to calculate the mass percent of each element. The formula to calculate the mass percent of an element A in a compound is as follows: Mass % of element A= ( ( Moles of A in formula ) ( Molar mass of A in g/mol ) Mass of 1 mol of compound in g ) ( 100 ) (1)

You have now performed a liquid-liquid extraction protocol in Experiment 4. In doing so, you manipulated and exploited the acid-base chemistry of one or more of the compounds in your mixture to facilitate their separation into different phases. The key to understanding how liquid- liquid extractions work is by knowing which layer a compound is in, and in what protonation state. The following liquid-liquid extraction is different from the one you performed in Experiment 4, but it uses the same type of logic. Your task is to show how to separate apart Compound A and Compound B. . Complete the following flowchart of a liquid-liquid extraction. Handwritten work is encouraged. • Draw by hand (neatly) only the appropriate organic compound(s) in the boxes. . Specify the reagent(s)/chemicals (name is fine) and concentration as required in Boxes 4 and 5. • Box 7a requires the solvent (name is fine). • Box 7b requires one inorganic compound. • You can neatly complete this assignment by hand and…
