<u>Answer:</u> The mass of sulfur hexafluoride is 146 u.
<u>Explanation:</u>
Mass of a mole of a substance is defined as the molar mass of that substance.
It is defined as the sum of every component each multiplied by the times they appear in that substance.
We are given:
Mass of sulfur atom = 32.0 u
Mass of fluorine atom = 19.0 u
The chemical formula for sulfur hexafluoride is 
So, the molar mass of 
Hence, the mass of sulfur hexafluoride is 146 u.
Halitic rocks have a large mineral layer of evaporite sedimentary rock, which is produced from drained lakes, playa and closed seas.
The difference between Halit rock layers and other rock layers is the element in it. The element in the Halit rock layer is sodium chloride.
<h2>Further explanation
</h2>
Halit Rock Layer is a type of salt, a mineral form (natural) from sodium chloride (NaCl) or better known as rock salt.
Knowledge about the layers of soil and rocks on the surface of the earth is stratigraphy. Stratigraphy is the study of the history, composition and relative age and distribution of bedding layers and the interpretation of rock layers to explain the history of the Earth.
