A. It does not retain the properties of the substances that make it up
To determine the amount of a substance in units of moles from units of grams, we need to determine the molar mass of the substance. <span>The </span>molar mass<span> is the </span>mass<span> of a given chemical element or chemical compound (g) divided by the amount of substance (mol). For CuF2, the molar mass </span><span>101.543 g/mol. We calculate as follows:
100.0 g CuF2 ( 1 mol / 101.543 g) = 0.98 mol CuF2</span>
Minerals, Because when wind blows everything and crushes rocks into minerals.

Answer:
18 km
Explanation:
To know the distance, you need to be clear in the concept of distance.
According to the physics, the distance is a measurement that refers to the fact of how much an object has move from one point to another.
In this case, we have a person named Steve and he's walking through several points.
To calculate the distance that he moved, you just need to sum all the values of distance. In this case, it's not neccesary to do calculations regarding the components of the x or y axis, because we are not talking about displacement, where it actually counts. But in this case, we just need all the covered distance that Steven walked since the beggining.
So, no more talk, let's do calculations:
D = 5 + 2 + 9 + 2 = 18 km
So the final answer would be:
<h2>
Distance = 18 km</h2>
Hope this helps
