Hey there!

It is evident that the problem gives the mass of the bottle with the calcite, with water and empty, which will allow us to calculate the masses of both calcite and water. Moreover, with the given density of water, it will be possible to calculate its volume, which turns out equal to that of the calcite.

In this case, it turns out possible to solve this problem by firstly calculating the mass of calcite present into the bottle, by using its mass when empty and the mass when having the calcite:

m_{calcite}=15.4448g-12.4631g=2.9817g

Now, we calculate the volume of the calcite, which is the same to that had by water when weights 13.5441 g by using its density:

V_{calcite}=V_{water}=\frac{13.5441g-12.4631g}{0.997g/mL}=1.084mL

Thus, the density of the calcite sample will be:

\rho _{calcite}=\frac{m_{calcite}}{V_{calcite}}\\\\\rho _{calcite}=\frac{2.9817g}{1.084mL}=2.750g/mL

This result makes sense, as it sinks in chloroform but floats on bromoform as described on the last part of the problem, because this density is between 1.444 and 2.89. g/mL

How many flourine atoms are present in 5.3 grams of flourine sample? (note that you have to use the 3 step method)​
Bingel [31]

Answer:

1.7x10²³ Fluorine atoms are present

Explanation:

To solve this question we must know that, to find the amount of atoms of a substance from its mass, we have, as first, to convert this mass to moles using molar mass of the substance. With the moles we can find the amount of molecules using Avogadro's number. And with the formula we can know the atoms presents:

<em>Moles Fluorine (F₂, Molar mass: 37.997g/mol)</em>

5.3g * (1mol / 37.997g) = 0.139 moles F₂

<em>Molecules F₂:</em>

0.139 moles F₂ * (6.022x10²³molecules / mol) = 8.4x10²² molecules F₂

As 1 molecule of F₂ contains 2 atoms of Fluorine:

8.4x10²² molecules F₂ * 2 =

<h3>1.7x10²³ Fluorine atoms are present</h3>
