How many moles are there in 28g of iron?
We know that, molar mass of an element is the atomic mass in grams. Hence, molar mass of iron is 56g. Thus, 0. 5 mole is present in 28g of iron.
How many grams are in iron?
Knowing that we have 0.013 moles of Fe, we could now convert that into grams by knowing that one mole of Fe has a mass of 55.85 grams; the yield would be 0.70 grams. We could also modify our basic set-up so that we could find the number of grams of iron directly.
How many particles are in iron?
For iron, Z=26 by definition; that is there are 26 protons, massive, positively charged particles, in the iron nucleus. Given the mass of the isotope, there must be 30 neutrons, massive, neutrally charged particles, in the iron nucleus (why must there be 30 neutrons?).

What is the molar mass of fe2o3?
How many moles are in he?
Explanation: The molar mass of helium (He) is 4.002602 g/mol (relative atomic mass on the periodic table in grams/mol), which means that one mole He has a mass of 4.002602 g .
How do you calculate grams to moles?
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.
How many grams are in a mole of Al?
One mole of Al atoms has a mass in grams that is numerically equivalent to the atomic mass of aluminum. The periodic table shows that the atomic mass (rounded to two decimal points) of Al is 26.98, so 1 mol of Al atoms has a mass of 26.98 g.
