The APsolute RecAP: Chemistry Edition - Empirical and Molecular Formulas
Description
Switching glucose and formaldehyde would be really bad (0:42 )! So let’s make sure we know the difference between empirical and molecular formulas! Our episode starts with a definition of empirical formulas (1:20 ) and the comparison of ionic and molecular compounds (1:49 ). It briefly recaps the significance of a chemical formula (2:16 ) and then recaps the steps to calculate an empirical formula using glucose as an example (2:50 ). But what if you do not have a whole-number ratio right away (5:30 ) and how do you go from Empirical to Molecular Formula (6:14 )? One specific type of calculation is the combustion analysis (7:11 ).
Question: What is the first step, if I have given grams of elements as part of the substance instead of % composition?
