Question

What is the density at STP of the gas sulfur hexafluoride, SF6?

O 3.93 x 1024 g/L
O 0.153 g/L
O 6.52 g/L
O 3270 g/L

Answer 1

Step-by-step explanation:

There is a formula for this:

M = DRT/P where M = molar mass. This just derived from PV = nRT where you say n = grams/molar mass. However, just with this formula, we can get D which is density at STP (1 atm and 273K). We find that D = 6.52g/L.

Answer 2

the third one... 6.52 g/L
