What is a carrier gas? Gas Chromatography: Gas chromatography refers to a chromatographic technique employed to separate and analyze vaporizable compounds without decomposing them. Examples of its applications include the detection of contaminants in pesticides and analysis of food additives. ...
Mole Ratio The mole ratio compares the number of moles in a balanced equation. This is the comparison between the coefficients in front of the chemical formulas. If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species. ...
Molar Mass Molar mass is the mass of one mole of a substance. We determine the molar masses from values on the periodic table. Answer and Explanation: Before we can sum all of the molar mass of the elements in acetic acid we need the chemical formula of acetic acid. Acetic acid's chem...
