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
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.
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 number of lead that has 127 neutrons?
209 since Lead is 82.
Which element has an atomic number 127?
It is not necessary to name it, unless it has been published....
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.
Molar mass of iodine-131?
Iodine is a non metal element. Atomic mass of it is 127.
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
Why does tellirium has a larger mass number than iodine?
Iodine is a non metal element. Atomic mass number of it is 127.
How neutrons are there in iodine?
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
What is the atomic number and atomic mass of iodine?
The atomic number of iodine (I) is 53.The atomic weight of I is 126.90 grams per mole.Iodine is a diatomic molecule, I2.See the Web Links to the left of this answer for a periodic table with more information about this element!
How many neutrons are there in iodine?
Number of neutrons = Mass number - Number of protons = 127 - 53 = 74
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
What element has 127 atomic mass?
Iodine is a non meta element. Atomic mass of it is 127.6.
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
What element has the atomic weight of 127?
