Answer:
To determine the number of atoms of Boron that are present within 3.61 grams of Boron Trifluoride, it would be best to convert the grams to moles of the compound and then after that use the Avogadro's number to determine the number of molecules and then use the 1 to 3 ratio to determine the total number of Boron atoms.
Answer:
<h2>Density = 5.24 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>

</h3>
From the question
mass = 52.4 g
volume = 10 cm³
Substitute the values into the above formula and solve for the density
That's
<h3>

</h3>
We have the final answer as
<h3>Density = 5.24 g/cm³</h3>
Hope this helps you
