Gasoline vapor is composed of gasoline molecules in the gas phase. Whatever the molecular mass of gasoline is in the liquid or solid phase, it is the same in the gas phase. Octane, C8H18, is the primary hydrocarbon in gasoline, We can use octane to answer this question. The molecular mass of C8H18 can be determined by multiplying the subscripts for C and H by the atomic weight of each element and adding the results: (8 x 12.011 u) + (18 x 1.008 u) =114.232 u
The molar mass of octane (C8H18), the primary component of gasoline, is approximately 114 g/mol. However, gasoline is a mixture of many hydrocarbons, some with as few as four carbons, while others have up to 12. According to US government agencies, such as DOE and EPA, on average, without adding any ethanol, the molar mass of gasoline is only 100 to 105 g/mol.
I assume you mean the molecular mass. Its molecular mass is 342.3g/mol
I assume you mean the molecular mass. Its molecular mass is 86.175
The molecular mass of cytosine is 111,10.
NO. Water has a density greater than gasoline, but gasoline, octane anyway, has a greater molecular mass than water molecules.
I assume you mean the molecular mass. Its molecular mass is 131.293g/mol

the relative molecular mass or molecular weight of a compound is the mass of a molecule of the compound relative to the mass of a carbon atom taken as exactly 12.
