y= 9/8 * x - 1
<span>Answer:
Since the pKb is is 4.75, the pKa is 9.25. Also, in the Henderson Hassalbalch, Molarity and moles are generally interchangeable if its the same solution.
pH = pKa + log (NH3/NH4Cl)
9.05 = 9.25 + log (Mole Ratio)
-0.2 = log (Mole Ratio)
10^-0.2 = Mole Ratio
Mole Ratio = 0.631
Now, that means for every mole of Acid, there are 0.631 moles of base. So we multiply the moles of base by the molar mass of NH3 and we multiply the moles of Acid by the molar mass of NH4Cl.
Base: 0.631 mol x 17.0 g/mol = 10.7 g NH3
Acid: 1.00 mol x 53.5 g/mol = 53.5 g NH4Cl
Now we just divide them to get the ratio.
10.7 g NH3 / 53.5 g NH4Cl = 0.200</span>

Answer:
ok so first we have to find out what the sample size is so
28+36+48+63=175
then lets find what percentage 28 is of 172
16.28
so ten lets find out how many that is out of the 1800
1800*0.1628=293.04
