The density of a certain gaseous fluoride of phosphorus is 3.93 g/L at STP. Calculate the molar mass of this fluoride and determine its molecular formula.
Added by Pedro B.
Step 1
First, we need to remember that at STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 L. This is known as the molar volume of a gas at STP. Show more…
