To answer this item, we assume that the gases are ideal for us to be able to use the ideal gas law.
PV = nRT
where P is pressure, V is volume, n is the number of moles, R is the universal gas constant and T is the temperature (in K)
Substituting the known values,
(0.963 atm)(6.92 L) = n(0.0821 L.atm/mol.K)(298 K)
The value of n from the equation is n = 0.27237 moles
We let x and y be the number of moles of NO2 and N2O4, respectively. Given the calculated total moles above and the total mass,
x + y = 0.27237
30x + 60y = 12.55
The values of x and y are:
x = 0.126 moles
y = 0.146 moles
The mole fractions of each gases are therefore:
mole fraction of NO2 = 0.126/(0.126 + 0.146) = 0.46
mole fraction of N2O4 = 0.146/(0.126 + 0.146) = 0.54
Lead(II) nitrate will react with iron(III) chloride to produce the precipitate lead(II) chloride as shown in the balanced reaction
2FeCl3(aq) + 3Pb(NO3)2(aq) → 2Fe(NO3)3(aq) + 3PbCl2(s)
Calculating the amount of the precipitate lead(II) chloride each reactant will produce:
mol PbCl2 = 0.050L Pb(NO3)2 (0.100mol/1L)(3mol PbCl2/3mol Pb(NO3)2)
= 0.00500mol PbCl2
mol PbCl2 = 0.050L FeCl3 (0.100mol FeCl3/1L)(3mol PbCl2/2mol FeCl3) = 0.00750mol PbCl2
The reactant Pb(NO3)2 produces a lesser amount of the precipitate PbCl2, therefore, the lead(II) nitrate is the limiting reagent for this reaction.
