Density of liquid hydrogen sulfide
Thread Content
What is the density of liquid hydrogen sulfide? I’ve searched through many sources but couldn’t find the answer. Could anyone with knowledge please advise me? Thank you
Such data is hard to find; please refer to the screenshot below:
Thank you for your reply, senior. I’ve also found this table, but I don’t quite understand it. What does “1, 15℃” in the upper right corner mean?

Since hydrogen sulfide has a lower polarity than water, intermolecular hydrogen bonding is not significant; as a result, its density is lower than that of water after liquefaction, although its molecular weight is greater than that of water.
That doesn’t make sense; this notation cannot be applied to every entry in the table – it might refer only to certain values. “1 atmosphere, 15 degrees” seems to describe the conditions of an open system. The table for hydrogen sulfide should show the density at the gas-liquid equilibrium state of a pure substance in a closed system, where the pressure increases as the temperature rises
