Question

Math toolbox:      ax2+bx+c =0  solve  ;         

                           1 cm3 = 0.001 dm3

The equilibrium constant is calculated Keq = 0.36 for the reaction @ 400 K when using M (mol/dm3) as the unit for the gasses. note: not the pressure unit.

          PCl5 (g) <=> PCl3 (g) + Cl2 (g)              

When using M as the units, the Keq is unitless with unit canceled to CѲ= 1 M.
 
Giving that 5.365 g of PCl5 (Mw = 208 g/mol) was initially placed in a reaction vessel of volume V = 250 cm3. When reach equilibrium, determine the molar concentrations of PCl3 in the mixture assuming ideal gasses for all.
 
concentration of PCl3 = ______ M.  3 sig. fig.
