Where would you find weak nuclear force? Why is the strong nuclear force significant for an atom? a
In the electrons of the atom; the strong nuclear force ensures protons and neutrons do not fly apart in the nucleus
b
the electron cloud; the strong nuclear force causes electrons to tightly bind to an atom.
c
When an ion is present: ions create stronger nuclear forces that allow electrons to move between elements
d
between the electron cloud and nucleus; the strong nuclear force keeps electrons and protons attracted to each other

How manyatoms of mercury are in 1.4214e+1 ml sample

A3.37-mg sample of protein was chemically digested to convert its nitrogen into ammonia and then diluted to 100.0 ml. then 10.0 ml of this solution was placed in a 50-ml volumetric flask and treated with 5 ml of phenol solution plus 2 ml of sodium hypochlorite solution. the sample was diluted to 50.0 ml, and the absorbance at 625 nm was measured in a 1.00-cm cuvette and found to be 0.486. for reference, a standard solution was prepared from 10.0 mg of nh4cl (molar mass = 53.49 grams/mole) dissolved in 1.00 l of water. then 10.0 ml of this standard was placed in a 50-ml volumetric flask, treated in the same manner as the unknown, and the absorbance found to be 0.323. finally, a reagent blank was prepared using distilled water in place of unknown, it was treated in the same manner as the unknown, and the absorbance found to be 0.076. calculate the weight percent of nitrogen in the protein.
