<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.

question: What is the speed of the cart?
Explanation:
The speed of an object in motion is the distance covered by the object with respect to time, that is, the ratio of distance covered to the time taken to reach that distance.
Speed = distance / time
= d (in meters m) / t (in seconds s) = m/s
