Zinc has 5 stable isotopes (64, 66, 67, 68, and 70), all of which are neutral atoms at standard temperature and pressure. Zinc has many more isotopes that are radioactive, but these too are usually neutral atoms.
Zinc-68 has 36 neutrons. This can be determined by subtracting the atomic number (number of protons) from the atomic mass (protons + neutrons), which for zinc is 68 - 30 = 38 neutrons.
it is about 68 to 69 depending on the atoms atomic mass
It depends on the isotope. Zn-64 and Zn-68 isotopes have 34 and 38 neutrons respectively.
There are 58 atoms in C18H32O18. This is calculated by adding up the total number of each element: 18 carbon atoms + 32 hydrogen atoms + 18 oxygen atoms.
There are 30 protons and 35 neutrons. This is true of the isotope Zinc-65 only. This isotope is produced synthetically. There are a total of seven zinc isotopes, five of which occur naturally and two that are synthesized. 64Zn has 34 neutrons 65Zn has 35 neutrons and is synthetic 66Zn has 36 neutrons 67Zn has 37 neutrons 68Zn has 38 neutrons 70Zn has 40 neutrons 72Zn has 42 neutrons and is synthetic

68
I believe this is correct, so hopefully this helps.... 68 kg is = 68,000 g. now take the substance you are dealing with a find it's molecular formula (the weight of each element in the formula). Divide 68,000g by the molecule weight (you just calculated). you now have the number of moles. 1 mole = 6.022X10^23 molecules/atoms... according to Avogadro's law.
sixty-eight 68 x 1 = 68
68 in = 5.67 ft
Answer: 68 " = 1.88888 yds.
