There are 126 g of Fe in 2.25 moles of Fe.
To calculate this, multiply 2.25 moles by 55.845 g (the atomic weight of Fe) over 1 mole. You then get 125.65125 g, but since the supplied number of moles has three significant digits, your final answer is 126 g.
The molar mass of iron (Fe) is approximately 55.85 g/mol. Therefore, the mass of 2.25 moles of iron can be calculated as 2.25 moles x 55.85 g/mol = 125.66 grams.
2.56 X 10^-3 moles iron (55.85 grams/1 mole Fe)
= 0.143 grams of iron
molar mass Fe = 55.845g/mol
2.25 moles Fe x (55.845g/mol) = 126g
The molar mass of iron is 55.845 g/mol. Multiply the moles of iron by its molar mass.
2.88 mol Fe x (55.845 g Fe)/(1 mole Fe)=161 g Fe (rounded to three significant figures)
