Explanation:
Because There are 6.022x10^23 atoms per mole; therefore, (6.022x10^23×3)=18.066x10^23 atoms of titanium.
Answer: The number of moles of excess reagent remain unreacted will be, 6.004 moles.
Explanation : Given,
Moles of 
= 1.332 mol
Mass of 
= 6.504 mol
First we have to calculate the limiting and excess reagent.
The balanced chemical equation is:
From the balanced reaction we conclude that
As, 13 mole of react with 1 mole of
So, 6.504 moles of react with 
moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Number of moles remain unreacted = 6.504 mol - 0.5003 mol = 6.004 mol
Therefore, the number of moles of excess reagent remain unreacted will be, 6.004 moles.
The empirical formula of the compound is SiCl₄.
<h3>Empirical formula of the compound</h3>
mass of silicon = 28 g/mol
mass of chlorine = 35.5 g/mol
<h3>molar ration: </h3>
Si = 8.56/28 = 0.306
Cl = 43.2/35.5 = 1.216
<h3>Combining ratio</h3>
Si = 0.306/0.306 = 1
Cl = 1.216/0.306 = 4
empirical formula = SiCl₄
Thus, the empirical formula of the compound is SiCl₄.

#SPJ1
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
