Calculation of Gram Atoms and Gram Molecules in 25.4gms of Iodine
Iodine is a diatomic element having a symbol I and atomic number 53. The atomic mass of iodine is 126.90g/mol. To calculate the number of gram atoms and gram molecules in 25.4gms of iodine, we need to follow the below-mentioned steps:
Step 1:
Calculate the number of moles of iodine present in 25.4gms of iodine.
Formula to calculate the number of moles:
Moles = Mass / Molar mass
Substituting the values in the above formula, we get:
Moles = 25.4gms / 126.90g/mol = 0.2 moles
Step 2:
Calculate the number of gram atoms of iodine present in 0.2 moles of iodine.
Formula to calculate the number of gram atoms:
Gram atoms = Moles x Avogadro's number
Substituting the values in the above formula, we get:
Gram atoms = 0.2 moles x 6.022 x 10^23 atoms/mol = 1.2044 x 10^23 atoms
Step 3:
Calculate the number of gram molecules of iodine present in 0.2 moles of iodine.
Formula to calculate the number of gram molecules:
Gram molecules = Moles x Molar mass
Substituting the values in the above formula, we get:
Gram molecules = 0.2 moles x 126.90g/mol = 25.38gms
Conclusion:
So, the number of gram atoms of iodine present in 25.4gms of iodine is 1.2044 x 10^23 atoms, and the number of gram molecules of iodine present in 25.4gms of iodine is 0.2 moles x 126.90g/mol = 25.38gms.

I=127g 127g=6.023*10^23 25.4g= x therefore, x= 25.4*6.023*10^23/127 = 0.2*6.023*10^23 gram molecules in 25.4g = 1.2046*10^23= gram atoms in 25.4 g
