Difference in formula mass and molecular mass
WebThe molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance's molar mass by summing the molar masses of its component atoms. We can then use the calculated molar mass to convert between mass and number of moles of the substance. Created by Sal Khan. WebAnswer (1 of 20): Not all substances are based on molecules. Many are, such as CO₂, H₂O, and CH₄, but many are ionic compounds that do not form true molecules, such as NaCl, and even many elements (C, Si, metals) do not form molecules. In CO₂, there are two specific oxygen atoms eachassociated wi...
