0The molar mass of iron is 55,845 g.Moles of iron = mass of iron/55,845

The mass of 4,00 moles of iron is 223,38 g.

The mass of 1.23 moles of iron is 58,69 g.

Molar mass of iron is 56g. Given mass of iron= 112g No. of moles = Given mass/Molar Mass => 112g/56g= 2 moles

0.10 moles iron (55.85 grams/1 mole Fe) = 5.6 grams of iron ==============

4 mols Fe * 55.845(mass of iron)=223.38g

Fe, or iron, has a molar mass of 55.845 grams per mole. This means that 0.2 moles is equal to 11.2 grams of iron.

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.

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

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

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

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

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 answer is 2,507 moles iron.

1 mole of iron atoms has the greatest mass - 55,845 g.

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

the equation you need is PV=nRTP=1.783 atmV=445 mL (convert to L by multiplying by .001)n=moles(what you're looking for)R=.08206T=225 (change Celsius to Kelvin by adding 273)solve for n to get the amount of moles and then multiply the moles by the molar mass of CO2 to get the mass :)

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.
