There are 48.72 g  Fluorine ions

<h3>Further explanation </h3>

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements

In the same compound, although from different sources and formed by different processes, it will still have the same composition/comparison

%F in CaF₂ :

\tt \%F=\dfrac{2.Ar~F}{MW~CaF_2}\times 100\%\\\\\%F=\dfrac{2.19}{78}\times 100\5=48.72\%

mass of Fluorine :

\tt 48.72\%\times 200=97.44~g

So mass Fluorine ions(2 ions F in CaF₂⇒Ca²⁺+2F⁻) :

\tt =\dfrac{97.44}{2}=48.72~g

If you have 40 grams of potassium nitrate in 100 grams of water at 20 C:
anygoal [31]

Answer:

Explanation:The final homogenous solution, after cooling it to 40°C, will contain 47 g of potassium sulfate disolved in 150 g of water, so you can calculate the amount disolved per 100 g of water in this way:

[47 g of solute / 150 g of water] * 100 g of g of water = 31.33 grams of solute in 100 g of water.

So, when you compare with the solutiblity, 15 g of solute / 100 g of water, you realize that the solution has more solute dissolved with means that it is supersaturated.

To make a saturated solution, 15 grams of potassium sulfate would dissolve in 100 g of water.

two samples of water, 10 grams and 50 grams are in sperate cups which of the following properties is different for the two boili
Trava [24]

Answer:

volume

Explanation:

The volume of the two samples of water will be different because volume is the amount of space occupied by a body. It is dependent on the amount of materials it contains.

  • The 50g sample will have a higher volume compared to the 10g sample.
  • The boiling point and density are intensive properties and do not depend on the amount of matter present.
  • Since both samples are from the same source, they will have the same color.
