You are given a protein solution with a concentration of 0.15 mg/ml.

v. suppose that we want to prepare 100 microliters of 10 micrograms/microliters solution. how much of h2o and protein stock do we need to add to obtain the target concentration and volume? (the concentration is not greater in the question, you need to convert it to micrograms/ then it should make sense)

6,666.66 micro liter of water and protein stock we will need to add to obtain the target concentration and volume.

Explanation:

Concentration of given solution

1 mL = 1000 μL , 1 mg = 1000 μg

The volume of the given solution =

Concentration of required solution =

Volume of required solution =

6,666.66 micro liter of water and protein stock we will need to add to obtain the target concentration and volume.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
