This problem is providing us with the mass equivalent to one troy ounce. Thus, the troy ounces of gold in one short ton of average Nevada ore is required and found to be the 0.103 otz according to the following dimensional analysis.
<h3>Dimensional analysis</h3>
In chemistry, a raft of problems do not always provide an equation in order to be solved yet dimensional analysis can be applied, so as to obtain the desired amount in the required units.
Thus, since this problem asks for try ounces in an average Nevada ore, which has 3.2 grams of gold per short ton of ore, one can solve the following setup in order to obtain the required answer in otz:
![\frac{3.2gAu}{1short-ton}*1short-ton*\frac{1otz}{31.1g} \\](https://tex.z-dn.net/?f=%5Cfrac%7B3.2gAu%7D%7B1short-ton%7D%2A1short-ton%2A%5Cfrac%7B1otz%7D%7B31.1g%7D%20%5C%5C)
Where the short tons are cancelled out as well as the grams, in order to obtain:
![0.103 otz](https://tex.z-dn.net/?f=0.103%20otz)

In terms of a deeper scientific reason, I am not sure, but the basic reason is quite simple. "Mud" tends to look like a mix between a solid, dirt, and a liquid, water or some other liquid. Since it is, in fact, a cross between a solid and a liquid, it has properties of both. It has certain physical and visual properties that only a solid would have, such as texture and opaqueness, but it also has physical properties of a liquid. Since it leans more towards the liquid side than the solid side, we say mud "flows" rather than saying that it "rolls" or "bounces".
