Phosphorus oxychloride weight?
« on: July 28, 2004, 03:18:00 AM »
Hello bees.
A bee wanted to know what is the weight of 1ml of phosphorus oxychloride. Alot of synths say to use XX ml of it.
The bee wants to replace the oxychloride with the oxybromide as it is more accesible to the bee. The bee knows it should perform the same, but the bee doesnt know how much phosphorus oxybromide to use, since its MP is 56degC and is not liquid at RT (phosphorus oxychloride MP is 1degC).
Can someone help the bee ?

Try google with the search terms "phosphorous oxychloride density".

densities are temperature dependant

Most densities are temperature dependant, so a proper density value should include the temperature at which it is measured. The higher density is likely mesured at 10-15°C and the other one at STP (25°C).
