1.5 g Fe times 55.8 g Fe (mass number) = .027 mol (in sig figs)
To find the number of moles, you need to divide the given number of iron atoms by Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. Therefore, for 5.22 x 10^22 iron atoms, the number of moles would be approximately 0.0867 moles.
To determine how many moles of bromide are in iron (III) bromide (FeBr3), you can use the chemical formula FeBr3 to see that there are three moles of bromide ions for every mole of iron (III) bromide. So, the number of moles of bromide ions is equal to the number of moles of FeBr3.
The number of moles is 4.
To find the number of moles, we need to divide the given mass of cobalt (382g) by its molar mass, which is approximately 58.93 g/mol. Therefore, 382g of cobalt contains approximately 6.48 moles of atoms.
There are approximately 3.25 x 10^24 iron atoms in 354 g of iron. This calculation is done by converting the mass of iron to moles using the molar mass of iron, and then using Avogadro's number to convert moles to atoms.
