Answer:
Concentration of the original solution: approximately
.
Explanation:
Notice that the concentration of the solution is in the unit
. However, the unit of the two volumes is
. Convert the unit of the two volumes to
to match the unit of concentration.
.
.
Calculate the number of moles of molecules in that
of
solution:
.
is a monoprotic acid. In other words, each
would release up to one proton
.
On the other hand, is a monoprotic base. Each
formula unit would react with up to one
.
Hence, molecules and
formula units would react at a one-to-one ratio.
.
Therefore, that of
molecules would neutralize exactly the same number of
formula units. That is:
.

Answer:
0.37 g
Explanation:
The molecular weight for Glycerol = 92
Number of Carbon atoms in glycerol (x) = 3
Molecular weight of the Biomass ( Klebsiella aerogenes )
=
=
= 26.1
From the molecular weight of the Biomass, we can deduce the Degree of reduction for the substrate(glycerol denoted as ) as follows:
= (4×1)+(1×1.73)-(2×0.43)-(3×0.24)
= 4.15
Given that the yield of the Biomass = 0.40 g
However;
C =
C =
C = 1.41 g
Now , the oxygen requirement can be calculated as:
=
=
= 2.1 g/mol
Hence, we can say that the needed oxygen = 2.1 g/mol of the substrate consumed.
Now converting it to mass terms; we have:
=
=
= 0.3652 g
≅ 0.37 g
∴ The oxygen requirement for this culture in mass terms = 0.37 g
