Benzene is a bit denser than gasoline, so volumetric vs mass vs molar basis aren’t directly comparable. This EPA slide deck [0] has ~1.25% by volume equated with ~1.5% by mass towards the conclusion slide. Interestingly it used to be around 5% benzene by volume before the newest standard. So 2% on a molar basis doesn’t seem obviously inconsistent with 1 vol% [0]: https://www.epa.gov/sites/production/files/2021-03/documents... |
