An Avogadro's number (6.022 x 10^23) worth of carbon atoms have that exact mass.
12.011 is the MOLAR mass of carbon. It is the mass of 1 mole of carbon. 1 mole of anything contains 6.022 x 10^23 of that thing.
1.5 × 10^-6 i would think
1 more of water requires 1 mole of hydrogen (H2) and 0.5 moles of oxygen (O2) . This requires 100/18 moles of hydrogen. As the molar mass of hydrogen is, 2 it requires 200/18= 100/9 g of hydrogen.
Explanation:
Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. Each nuclesome is composed of DNA wound 1.65 times around eight histone proteins.
