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.
The mass number is the number of protons and neutrons in the nucleus. As isotopes of an element have differing numbers of neutrons you must always check what isotopes exist.
Indium has a number of stable isotopes:
113In with 64 neutrons, 39 protons and % in nature of 4.3%
115In with 66 neutrons, 39 protons and % in nature of 95.7%
I = 126.9 ~ 127
Molecular Formula of Iodine = I2
therfore 1 mole of iodine = 127 x 2 = 254
Iodine is a metal element. Atomic mass of it is 127.
Indium is a metal element. Atomic mass of it is 49.
1atom I x (1mol I/6.022 X 10^23) x (128.90g I/1mol I)= 2.140 x 10^-22
Indium is a metal element. Atomic mass number of it is 115.
Indium (In) has an atomic weight of 114.818g/mol
Mass of Iodine is 126.9045

There is one mole of iodine in one mole. There are 126.90447grams of iodine in one mole. There are also 6.022x1023 atoms in one mole.
32 grams, you can find the mass of one mole of any element by looking at its atomic mass eg chlorine has Atomic mass of 35.5 so the mass of one mole of chlorine is 35.5 grams.
HI, A MOLE IS MOLECULAR MASS. MOLECULAR MASS OF SODIUM IS 23. HENCE, 1.22 MOLE = 1.22*23 = 28.60
By definition, one mole would be the same as the atomic mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.S- 32.1O- 16.0SO- 48.1 grams in one mole
Silicon carbide has the formula SiC. The mass of 1 mole would be 28 + 12 = 40 g/mole
There is one mole of iodine in one mole. There are 126.90447grams of iodine in one mole. There are also 6.022x1023 atoms in one mole.
Iodine is a non metal element. Atomic mass of it is 127.
Fairly heavy! 1.14 X 1024 atoms of iodine ( 1 mole I/6.022 X 1023)(126.9 grams/1 mole I) = 240 grams of iodine -------------------------------

Gold, as it has the higher molar mass.
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
Gold
32 grams, you can find the mass of one mole of any element by looking at its atomic mass eg chlorine has Atomic mass of 35.5 so the mass of one mole of chlorine is 35.5 grams.
Balanced equation. Zn + I2 --> ZnI2 All is one to one, so it does not matter what is limiting and what drives this reaction. We will use zinc as the driver of convenience. 1 mole Zn (1 mole ZnI2/1 mole Zn)(319.21 grams/1 mole ZnI2) = 319.21 grams zinc iodide produced ==========================
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.
The mass of one mole of substances
.005078 g is the weight of 2 mole percent molecular iodine.
