There are approximately 3.2 billion atoms in a single strand of human hair.
No one knows how many atoms are in a sponge. There has to be billions of atoms because in one strand of your hair there is about a million atoms.
70,000 molecules in one hair strand ( average length, to shoulder)
For every 15 X atoms in the compound X3Y, there would be 3 Y atoms. This is because the ratio of X to Y in the formula is 3:1, so for every 3 X atoms, there is 1 Y atom.
No, the chemical formula for water is H2O. This means that for every oxygen atom in the compound, there are two hydrogen atoms. Thus, the number of hydrogen atoms in water is double the number of oxygen atoms.
You would need to line up about 2,500,000 aluminum atoms to match the width of a human hair. This is because the width of a human hair is typically around 70 micrometers, and an aluminum atom is about 0.28 nanometers in diameter.
More than a million is all I know.
every strand live 6 years, one at a time and then will grow another.
An average of 100,000 hair strands.
100,000

I have been searching for the answer to this question for years. Every once in a while I will find a strand of hair that is striped, alternating silver and dark brown. I have naturally dark brown, very curly hair, and I can't find the answer to this. I know that this doesn't answer your question, but I've been searching as well!
There are many ways that hair extensions are affixed to your own natural hair. If your are talking about strand by strand hair extensions, my favorite way to attach them is with a keratin bond that sits close to your scalp but not so close as it pulls or tugs on your natural hair as that can cause serious hair loss.
Approximately 1 million atoms can fit across the width of a human hair.
every and any DNA strand can constitue to a chromosome :)
Suppose:formula of 'hair' is (averaged by) C10H18O5N2S and so this is with 36 atoms in one 'molecule'Its formula mass is (averaged by) [10*12.0+18*1.0+5*16.0+2*14.0+1*32.0] = 260 g/moland the mass of one hair is (averaged by) 1.0 mgThe answer can now be calculated, (controlled by 'unit analysis')[1.0*10-3(g) / 260(g/mol)] * 6.022*10+23(molecules/mol) * 36 (atom/molecule) =8*10+19 atoms (+/- 10%) per hair of 1 mg.
2 atoms of hydrogen for every atom of oxygen.
