Answer:

60.5 L

Explanation:

If the gas temperature is constant, we can use Boyle's law:

P1V1 = P2V2

V2 = P1V1 / P2

P1 = 12.7 kPa

V1 = 40.0 L

P2 = 8.4 kPa

V2 = (12.7 kPa) (40.0 L) / (8.4 kPa) = 60.5 L

Iron in the 2 oxidation state reacts with potassium dichromate to produce Fe3 and Cr3 according to the equation: 6 Fe2 (aq) Cr2O
allsm [11]

Given :

Volume of Fe^{2+} , V = 132 mL .

Molarity of Fe^{2+}, M = 0.1782 M .

To Find :

How many milliliters of 0.2937 M K_2Cr_2O_7 are required to titrate 132.0 mL of 0.1782 M Fe^{2+} solution .

Solution :

Moles of  Fe_2 :

n=0.1782\times \dfrac{132}{1000}\ mol\\\\n=0.264\ mol

Now , 1 mole of K_2Cr_2O_7 reacts with 6 mole of Fe^{2+} .

So , moles of K_2Cr_2O_7 required is :

N=\dfrac{0.264}{6}=0.044\ mol

Volume required is :

V=\dfrac{N}{M}\\\\V=\dfrac{0.044}{0.2937}\ L\\\\V=0.15\ L=150\ mL

Hence , this is the required solution .
