Avogadros number of Sulfur atoms would have a mass of? If the question is asking for the Avogadros number, its 6.02 x 10^23. If the question is asking for the mass of sulfur its 32 g/mol. The question seems to be asking for the mass of an Avogadros number, which doesn't make sense because Avogadros number is not a mass measurement.

Isotopes The total number of protons and neutrons in an atom is called its mass number. Chemical symbol of chlorine-35. The proton number is shown below the chemical symbol, and the mass number is shown above. In this example the atomic number is 17 and the mass number is 35. This means that each of these atoms has: 1  17 protons. 2  17 electrons.  35 - 17 = 18 neutrons.

Zinc Different forms of zinc contain different amounts of elemental zinc, which refers to the weight of the zinc molecule by itself (Note: Product labels tend to mark the elemental weight) Zinc citrate is approximately 34% zinc by weight. For a dose of 50mg elemental zinc, take 146 mg zinc citrate. Zinc sulfate is approximately 22% zinc by weight. For a dose of 50mg elemental zinc, take 220 mg zinc sulfate. Zinc gluconate is approximately 13% zinc by weight. For a dose of 50mg elemental zinc, take 385 mg zinc gluconate. Zinc monomethionine is approximately 21% zinc by weight. For a dose of 50mg elemental zinc, take 238 mg zinc monomethionine. Zinc should be supplemented daily. Superloading zinc by taking up to 100mg zinc a day is confirmed to be safe in the short term (2-4 months), but because this dose is higher than the 40mg Tolerable Upper Limit (TUL) of zinc, prolonged superloading is not advised.

Atomic Number and Mass Number Atomic Number (Z) = Number of protons =Number of electrons. For example, an atom of magnesium contains 12 protons, therefore, its atomic number is 12. All the atoms of a particular element contain same number of protons in their nuclei. Therefore, all the atoms of an element have same atomic number.

Zinc Zinc is a chemical element with symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table. In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes.
