Web19 de ago. de 2024 · What is the molar mass of H 2 O? Solution (1) Molar mass = 2 × ( 1.00794 g / m o l) + 1 × ( 15.9994 g / m o l) = 18.01528 g / m o l Using molar mass and coefficient factors, it is possible to convert mass of reactants to mass of products or vice versa. Example 5: Combustion of Propane Propane ( C 3 H 8) burns in this reaction: WebFor compounds that are not molecular (ionic compounds), it is improper to use the term “molecular mass” and “ formula mass” is generally substituted. Air is a mixture of several gases, where the two most dominant components in dry air are 21 vol oxygen and 78 vol nitrogen. The molar mass of the N 2 molecule is therefore 28.02 g/mol.
