The [α] of pure quinine, an antimalarial drug, is −165. If a solution contains 86% quinine and 14% of its enantiomer (ee = 72%),

ratelena [41]

Answer : The [α] for the solution is, -118.8

Explanation :

Enantiomeric excess : It is defined as the difference between the percentage major enantiomer and the percentage minor enantiomer.

Mathematically,

$\%\text{ Enantiomer excess}=\%\text{ Major enantiomer}-\%\text{ Minor enantiomer}$

Given:

% major enantiomer = 86 %

% minor enantiomer = 14 %

Putting values in above equation, we get:

$\%\text{ Enantiomer excess}=86\%-14\%=72\%$

$\text{ Enantiomer excess}=\frac{72}{100}=0.72$

Now we have to calculate the [α] for the solution.

$[\alpha]=\text{Enantiomer excess}\times [\alpha]_{Pure}$

$[\alpha]=0.72\times -165$

$[\alpha]=-118.8$

Thus, the [α] for the solution is, -118.8

What is the [oh−] of a solution if its ph = 8.78? answer in units of m?

dexar [7]

PH = -log([H+])
[H+] = 10^(-pH)

[H+] = 10^(-8.78) = 1.65*10^-9

[H+][OH-] = Kw
Kw = 1.0*10^-14 at 25 degrees celsius.

[OH-] = Kw/[H+] = (1.0*10^-14)/(1.65*10^-9) = 6.06*10^-6

The concentration of OH- ions is 6.1*10^-6 M.

ololo11 [35]

Answer:

P2 = P1*n2 / n1

=1.02 atm *0.008 moles / 0.00113 moles

= 7.22 atm

∴the new pressure will be 7.22 atm
