1,4-Pentadiene (CH2=CH-CH2-CH=CH2) is a liquid at room temperature and has a density of 0.66 g/mL and molar mass of 68.12 g/mol. In a laboratory experiment, 3.80 mL of this compound was treated with 4.80 mL of conc. H2SO4 (100% w/w; molar mass 98.08 g/mol). Note that the density of conc. H2SO4 is 1.84 g/mL. The resulting sulfate ester was then treated with 1.20 mL of water (molar mass 18.02 g/mol) affording, after work- up, 2,4-pentanediol (molar mass 104.15 g/mol) as the crude product.
