What mass of Iodine contains same number of atoms as 50.0g of Cl?
Let I = Iodine
If the number of moles of Cl are equal to the number of moles of I, then they will have the same number of atoms.
50.0g of Cl *(1mole of Cl/35.45 g of Cl)= moles of Cl
moles of Cl=moles of I
moles of I *(126.9 g of I/1 mole of I)= mass of I where atoms are the same in I as they are in 50..g of Cl.
I'm confused by that last part. I got that there are 1.41 mol of Cl but I don't understand what the number 126.9g of I/ 1 mol of I is up against.
You know that 1 mole=6.02 x 10^23 atoms and one mole equals the molecular weight of a compound.
1 mole of Iodine=126.9g of iodine.
Since the moles of Cl=moles of Iodine then,
the number of moles of Iodine multiplied by the molecular weight of Iodine will give you the mass of iodine where Iodine will have the same amount of atoms as Cl.
Thank you!
To determine the mass of iodine that contains the same number of atoms as 50.0 grams of chlorine (Cl), we can use the concept of molar mass and Avogadro's number.
1. Find the molar mass of chlorine (Cl). The molar mass of chlorine is approximately 35.45 grams per mole (g/mol). This value can be found on the periodic table.
2. Calculate the number of moles of chlorine (Cl) in 50.0 grams of chlorine by dividing the given mass by the molar mass:
Number of moles = Mass / Molar mass
Number of moles of Cl = 50.0 g / 35.45 g/mol ≈ 1.41 moles
3. Since iodine (I) and chlorine (Cl) are both halogens, they have the same number of atoms per mole.
4. Finally, we can calculate the mass of iodine using the number of moles of chlorine (Cl):
Mass = Number of moles × Molar mass
Mass of I = 1.41 moles × 126.90 g/mol ≈ 178.97 grams
Therefore, the mass of iodine that contains the same number of atoms as 50.0 grams of chlorine is approximately 178.97 grams.
