Hello, my name is john, and for this question, we have to find the molar mass of this fluoride and determine its molecular formula.
00:07
So the first thing that we're going to do is use the equation pv is equal to nrt and solve for n at stp.
00:14
So it's going to be 1 atm.
00:16
We're going to use the density scenario, so 1 liter, is going to equal n, which is what we're trying to find, multiplied by the r constant, multiplied by the stp temperature.

Once we plug this in our calculator, we get the amount of moles to be approximately, the 0 .0 -4464 moles of pfx.
00:39
And what we're trying to find here is the molecular formula.
00:42
So we're going to put the suffix as x as well...
