Calculate the equilibrium concentration of the nonionized bases and all ions in a solution that is 0.25 $\mathrm{M}$ in $\mathrm{CH}_{3} \mathrm{NH}_{2}$ and 0.10 $\mathrm{M}$ in $\mathrm{C}_{5} \mathrm{H}_{5} \mathrm{N}\left(K_{\mathrm{b}}=1.7 \times 10^{-9}\right)$

$1.06 \times 10^{-2} \mathrm{M}$$1.43 \times 10^{-8} \mathrm{M}$

we have the equilibrium, concentration and equilibrium. Constant expression which are represented here. The Gaby is much larger for CS. Three minutes to then C five h five n first equilibrium will donate will dominate. It is provided by CH three An edge to concentration, and we have the K B value. Let X be the change in concentration when the reaction is reached at equilibrium. Thus, the concentration at equilibrium can be expressed as as follows. Here. Exit E present The Moler Saul Ability. No to calculate the moola. Solely ability. Applying the assumption that the concentration off see history an edge to is equal to 0.25 minus X almost equivalent to 0.25 substituting in the value to the association Constant for us, it ex turns out to be 1.6 Entertainment's over minus two because this value is 4.24 off 0.25 Our assumption is correct. This is only valid for values less than 5%. The concentration off CH three and it's two. Turns out Toby, 20.25 finally used the other equilibrium to find the concentration here. X cannot be negligent. Neglected in comparison with C five h five n concentration because it is more than 5% off initial concentration. We have the given concentration as follows, substituting these values into the formula. The concentration off Psi Phi, which five and Mitch positive turns out to be for 1.43 in two tender super minus eight hence. Thus, the concentration off non ionized asset is shown on the concentration off Ryan's is over here.
