Wenzhou prepares 200 mL of a solution of SnCl4in which the concentration ofchloride ions is 0.240M.a) What is the molarity of th
nalin [4]

Answer:  a) 0.06 M

b) 3.13 grams.

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Molarity=\frac{moles}{\text {Volume in L}}

Moles of  Cl^-=Molarity\times {\text {Volume in L}}=0.240\times 0.2L=0.048moles

The balanced reaction for dissociation will be:

SnCl_4\rightarrow Sn^{4+}+4Cl^{-}

Thus for 4 moles of Cl^-, there is 1 mole of SnCl_4

Thus moles of SnCl_4=\frac{1}{4}\times 0.048=0.012

Molarity of SnCl_4=\frac{moles}{\text {Volume in L}}=\frac{0.012}{0.2L}=0.06M

Thus the molarity of the  SnCl_4 solution = 0.06 M

b) Mass of SnCl_4= moles\times {\text {Molar mass}}=0.012mol\times 260.522g/mol=3.13g

Thus mass of  SnCl_4 Wenzhou use is 3.13 grams.
