Great question, but I believe you are mixing up atomic number with mass number. Assuming you are, 12.011 amu is the average mass of a carbon atom. For carbon, it can come in three forms: carbon-12, carbon-13, carbon-14. The number following carbon is the mass number of that particular carbon "isotope". The reason the average is so close to 12 is because carbon-12 is by far the most common, so the average should be (and is) very close to 12. Therefore, 12.011 is a weighted average of all carbon molecules, and carbon-14 is a particular carbon molecule that weighs 14 amu.
Answer:
pH ( potential Hydrogen ) is a negative logarithm of molar concentration of hydrogen ions.
therefore:
What that question makes 0 sense and there is no picture
You have the neurons, osteoblasts, machrophages, red blood cells, and myocytes.
