How many times is fluorine heavier than air?

Fluorine is a chemical element of DI Mendeleev’s Periodic Table of Chemical Elements with serial number 9. The simple substance fluorine has the formula F2, that is, it consists of two atoms of the chemical element fluorine and has a molar mass of 38 g / mol. The average molar mass of air is approximately 29 g / mol. To find out how many times a gas fluorine is heavier than air, we divide the molar mass of fluorine by the molar mass of air. Rounding off the result, we get the number 1.31, that is, a simple substance – fluorine gas – is 1.3 times heavier than atmospheric air.
