23.For a 0.1Maqueous solution of sodium acetate,Na+H3CO2-, one mass alance is simply[Na+]=0.1M. Write a mass balance involving acetate.

Short Answer

Expert verified

The mass balance involving acetate is given by CH3CO2H+CH3CO2-=0.1M.

Step by step solution

01

Definition of mass balance

The mass balance states that the quantity of all species in a solution containing a particular atom (or group of atoms) must equal the amount of that atom (or group) delivered to the solution.

02

Balancing the mass for given solution

Read and understand the following to come up with a mass balance

involving acetate:

(1)If the acetate does not react any further,CH3CO2-=0.1M

(2) However,1 mole of the CH3CO2-reacts with water to form 1

mole ofCH3CO2-.

So, the mass balance is CH3CO2H+CH3CO2-=0.1M.

Therefore, the mass balance involving acetate is given by

CH3CO2H+CH3CO2-=0.1M.

Molecular mass by sodium dodecylsulfate–gel electrophoresis. Ferritin is a hollow iron-storage protein 74 consisting of 24 subunits that are a variable mixture of heavy (H) and light (L) chains,arranged in octahedral symmetry. The hollow center, with a diameter of 8 nm, can hold up to 4 500 iron atoms in the approximate form of the mineral ferrihydrite (5Fe1O3×9H2O)Iron(II) enters the protein through eight pores located on the threefold symmetry axes of the octahedron. Oxidation to Fe(III) occurs at catalytic sites on the H chains. Other sites on the inside of the L chains appear to nucleate the crystallization of ferrihydrite. Migration times for protein standards and the ferritin subunits are given in the table. Prepare a graph of log(molecular mass) versus 1/(relative migration time), where relative migration time 5 (migration time)/(migration time of marker dye). Compute the molecular mass of the ferritin light and heavy chains. The masses of the chains, computed from amino acid sequences, are 19 766 and 21 099 Da.
