Calculate the mass of chloroform actually injected onto the GC column when you injected pure chloroform at the beginning. To do this you will need the volume injected, the split ratio, and the density of the compound. The split ratio is the volume injected that does not go to the column (and is vented instead) for every volume that does go onto the column. For example, if the split ratio is 100:1, then only 1/101 of the amount injected from the syringe actually goes onto the column (one part to the column, 100 parts vented). Express the answer in micrograms.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
