caculate the number of moles in 8200 g of iron
moles = grams/molar mass
can u show me how to set it up because i don't get it at all
What is there to get.
moles = grams/molar mass.
g is given to you (8200 g).
molar mass of Fe you obtain from the periodic table. Look it up. I think it's about 55 or something like that.
And you divide one number by another. Don't try to make this harder than it is. If you can divide 4/2 you can do this.
I want to know what is the answer
cant uanswer it
To calculate the number of moles in a given mass of a substance, we need to use the formula:
moles = mass / molar mass
Step 1: Find the molar mass of iron (Fe)
The molar mass is the mass of one mole of a substance in grams. To find the molar mass of iron, we need to look up the atomic mass of iron from the periodic table. The atomic mass of iron (Fe) is approximately 55.85 g/mol.
Step 2: Calculate the number of moles using the formula
moles = mass / molar mass
Given: Mass of iron = 8200 g
moles = 8200 g / 55.85 g/mol
moles = 147.007 mol (rounded to three decimal places)
Therefore, the number of moles in 8200 g of iron is approximately 147.007 mol.
