A mole of an element is X grams of the element, where X is the number of the elements atomic mass. The atomic mass of iron is 55.85, so one mole of iron is 55.87 grams. Two moles of iron is 111.7 grams. 101.7 grams is 101.7/55.85 moles = 1.82 moles.

molar mass Fe = 55.845g/mol 2.25 moles Fe x (55.845g/mol) = 126g

Iron chloride has a molar mass of 162 grams per mole. To find the number of moles, divide the mass of the sample by the molar mass.

The molecular mass of iron III nitrate is 241.86g/mol. Mass divided by molecular weight gives moles, which is 0.02481 moles (6/241.86)

Given: The molar mass of Iron is 55.85g/mol Therefore, 34.0g x 1 mol/55.85g = 0.609 moles

The molar mass of Aluminium hydroxide is 78 g/mol. Therefore there are 5.12 moles in 400 grams of aluminium hydroxide.

To calculate the number of moles from grams, you must divide by the substance's molar mass

The atomic mass oof iron is 56a.m.u so 56g iron means 1 mole of iron.

How many moles of iron atoms are contained in 4.09g of iron

okay, it does not tell us how much iron reacted with oxygen, so we assume that iron reacted completely. just convert grams iron used into moles. 85.65g Fe/55.85g Fe X 1 mole Fe = 1.534 moles Fe btw the empirical formula you should get is Fe3O4

Let's see. 3 moles gold (197.0 grams/1 mole Au) = 591 grams of gold ----------------------------- 10 mole iron (55.85 grams/1 mole Fe) = 558.5 grams of iron ----------------------------- So, 3 moles of gold has more mass that 10 moles of iron. (heavier)

The molar mass of Fe2O3 is 55.845 (molar mass of iron)*2+16(molar mass of oxygen)*3, which comes out to be 159.69 grams per mole. Multiply that by the number of moles, and the answer is 223.57 grams.

2.56 X 10^-3 moles iron (55.85 grams/1 mole Fe) = 0.143 grams of iron

For this you need the atomic mass of Fe. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.82.5 moles Fe / (55.9 grams) = 1.48 moles Fe

To convert mass to moles, you use the equation n= m/M n is moles, m is mass, M= Molar mass, which is the mass of the atoms in the formula or substance.

This formula is: moles = mass of the compound/molar mass of the componnd
