For this you need the atomic (molecular) mass of I2. Take the number of grams and divide it by the Atomic Mass. Multiply by one mole for units to cancel. I2=253.8 grams
12.7 grams I2 / (253.8 grams) = .0500 moles I2

What is the weight of iodine?
gram-Equivalent of iodine is 127 because its molecular weight is 2(127) and 2 electron change involve in the redox titration
How many atoms are in 127 g of calcium?
The gram atomic mass of calcium is 40.08. Therefore, 127 g of calcium constitutes 127/40.08 or 3.69 gram atomic masses. By definition of Avogadro's Number, each gram atomic mass contains Avogadro's Number of atoms. Therefore, the answer is 3.69 X Avogadro's Number or 1.91 X 1024 atoms, to the justified number of significant digits.
What is the mass of one mole of Iodine?
The number 115 is the mass number, so the mass is 115 amu. One amu (atomic mass unit) is about 1.66 x 10-27 kg, so if your looking for the mass of one atom of In-115, multiply 1.66 x 10-27 kg by 115. That's about 1.9 x 10-25 kg. You chemistry teacher should have taught you this, and probably did, if you were paying attention in class.
What is the mass number of lead that has 127 neutrons?
The mass number of an atom is the sum of its protons and neutrons. Lead (Pb) has an atomic number of 82, so it has 82 protons. If it has 127 neutrons, the mass number would be 82 (protons) + 127 (neutrons) = 209.
Which element has an atomic number 127?
It is not necessary to name it, unless it has been published....
What is the mass of 10 moles of iodine atoms?
Iodine has a molar mass of 129.9g So one mol of Iodine is 129.9g. Therefore 10 moles of iodine would be 1299g.
Find the moles of I2 in 450 grams of I2?
To find the number of moles in I2, we have to know the atomic weight of iodine (which my periodic table tells me is 127). But iodine is a diatomic element, existing in molecules of 2 iodine atoms bound together (I2). So the molecular weight of I2 is 2 x 127 = 254g/mole. Moles = mass/MW, so moles = 450g/(254g/mole). The "grams" cancel out and the answer is 1.77 moles.
How many neutrons does iodine cost?
Iodine typically has an atomic number of 53, which means it has 53 protons. The most common isotope of iodine, iodine-127, has 74 neutrons. To find the number of neutrons in an isotope, you subtract the atomic number from the mass number; for iodine-127, that calculation is 127 (mass number) - 53 (atomic number) = 74 neutrons.
What is the weight of iodine?
gram-Equivalent of iodine is 127 because its molecular weight is 2(127) and 2 electron change involve in the redox titration
Why does tellirium has a larger mass number than iodine?
Iodine is a non metal element. Atomic mass number of it is 127.
How many neutrons are there in iodine?
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
How neutrons are there in iodine?
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
What is the isotope iodine 75?
There is no such isotope (75) known. Iodine (atom number 53, average atomic mass 127) has 53 protons and 70 up till 82 neutrons. The lowest known isotope number therefor is 123.
Iodine atomic number and atomic mass?
the atomic number is 53 and the atomic mass is 126.9 so you would round it up to 127
How many protons neutrons and electrons are in iodine?
Iodine has an atomic number of 53, which means it has 53 protons and, in a neutral atom, also 53 electrons. The most common isotope of iodine, iodine-127, has 74 neutrons (127 - 53 = 74). Therefore, in a neutral iodine-127 atom, there are 53 protons, 53 electrons, and 74 neutrons.
What is the molecular mass of iodine pentafluoride?
The atomic mass of I is 127. The atomic mass of F is 19. Therefore the molecular mass of the compound is 127+5x19=214u.
The iodine isotope with 74 neutrons?
An isotope of iodine with 74 neutrons would have a mass number of 53 +74 = 127. Therefore its symbol would be I -127 or 127 C 53. 127 and 53 should be written as superscript and subscript respectively before writing the chemical symbol of iodine when using the later (127 C 53).Ê 53 is the atomic number of iodine.ÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊÊ
