Answer:
A mole ratio is the ratio between the amounts in moles of any two compounds involved in a chemical reaction. ... The mole ratio may be determined by examining the coefficients in front of formulas in a balanced chemical equation. Also known as: The mole ratio is also called the mole-to-mole ratio.

Answer:
The answer to your question is: SiCl₄
Explanation:
Data 
amount of Si      1.71 g
amount of Cl     8.63 g
MW Si = 28 g
MW Cl = 35.5
Process (rule of three)
For Si                                                        For Cl 
         28 g of Si ------------------ 1 mol                      35.5 g of Cl --------------- 1 mol
           1.71g of Si  ---------------   x                              8.63 g of Cl --------------  x
          x = 1.71 x 1 / 28 = 0.06 mol                          x = 8.63 x 1 / 35.5 = 0.24 mol
Now, divide both results by the lowest of them.
Si = 0.06 mol / 0.06 = 1 molecule of Si     Cl = 0.24 / 0.06 = 4 molecules of Cl
Finally 
                      Si₁ Cl₄ or SiCl₄
 
        
             
        
        
        
You can use a graduated cylinder.
