1 mole Fe * 56 g Fe
...............1 mole Fe
The molar mass of iron is 55.85 g/mol. To find the weight of 7.4 moles of iron, you would multiply the number of moles by the molar mass. Therefore, 7.4 moles of iron would weigh 7.4 moles * 55.85 g/mol = 411.49 grams.
To calculate the amount of iron that can be recovered from FeO, we need to consider the molar ratio between Fe and FeO. FeO consists of 1 iron atom and 1 oxygen atom. The molar mass of Fe is 55.85 g/mol, and the molar mass of FeO is 71.85 g/mol. By dividing the molar mass of Fe by the molar mass of FeO and multiplying by the given mass of FeO, we can determine the amount of iron that can be recovered.
The equation of the reaction is Fe + HCl → H₂ + FeCl₂. Since one mole of iron produces one mole of hydrogen gas, the molar ratio between Fe and H₂ is 1:1. Thus, the total number of grams of H₂ produced when 116 grams of iron is reacted would be 2 grams (1 mole of hydrogen gas weighs 2 grams).
Known/Given:1 mole of Fe = 55.845g Fe (its atomic weight in grams)1 mole of Fe = 6.022 x 1023 atoms Fe (from Avogadro's number)Convert grams Fe to moles Fe.600.0g Fe x 1mol Fe/55.845g Fe = 10.74mol FeConvert moles Fe to atoms Fe.10.74mol Fe x 6.022 x 1023atoms Fe/1mol Fe = 6.468 x 1024atoms Fe
To convert moles to grams, you need to multiply by the molar mass of the element. The molar mass of Fe (iron) is approximately 55.85 g/mol. For 24.6 moles of Fe, the mass in grams would be 24.6 moles x 55.85 g/mol = 1373.31 grams (approximately).
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..410 grams Fe / (55.9 grams) = .00733 moles Fe
The atomic mass of iron (Fe) is approximately 55.85 grams per mole.
The molar mass of iron is 55.85 g/mol. To find the weight of 7.4 moles of iron, you would multiply the number of moles by the molar mass. Therefore, 7.4 moles of iron would weigh 7.4 moles * 55.85 g/mol = 411.49 grams.
What is the chemical 'FE'. Do you mean 'Fe'. If so to answer your question . The molar mass of iron (Fe) is 55.845
Use the equation; mass=moles*gramformulamass or m=n*gfm m=2*55.8 = 111.6g in two moles of Iron gfm or the molecular mass of a compound can be found by adding the Relative atomic masses of each element in the compound together. For example - Carbon dioxide CO2 The formula contains 1 Carbon atom and 2 Oxygen atoms (RAMs should be found in a datasheet/book or provided in the question. RAM = relative atomic mass) RAM Carbon = 12 RAM Oxygen = 16 gfm of CO2 = 12 + 32 = 44 or 1mole of CO2 = 44g
To calculate the amount of iron that can be recovered from FeO, we need to consider the molar ratio between Fe and FeO. FeO consists of 1 iron atom and 1 oxygen atom. The molar mass of Fe is 55.85 g/mol, and the molar mass of FeO is 71.85 g/mol. By dividing the molar mass of Fe by the molar mass of FeO and multiplying by the given mass of FeO, we can determine the amount of iron that can be recovered.
The equation of the reaction is Fe + HCl → H₂ + FeCl₂. Since one mole of iron produces one mole of hydrogen gas, the molar ratio between Fe and H₂ is 1:1. Thus, the total number of grams of H₂ produced when 116 grams of iron is reacted would be 2 grams (1 mole of hydrogen gas weighs 2 grams).
Based on the balanced chemical equation 2Fe + 3S -> Fe2S3, the molar ratio of Fe to S is 2:3. First, convert the 48.0 grams of sulfur to moles, then use the molar ratio to find the moles of iron needed. Finally, convert the moles of iron to grams to determine the required amount of iron.
To find the number of moles of Fe in Fe2O3, first calculate the molar mass of Fe2O3 and O. Then, determine the number of moles of O in the sample. Finally, you can use the stoichiometry of Fe2O3 to find the moles of Fe present. Alternatively, if you know the molar mass of just Fe, you can calculate the moles of Fe by dividing the mass of Fe in the sample by its molar mass.
To do this, you need to know the atomic weight of the element you're dealing with, found on any periodic table. The atomic weight is the mass in grams of the element in one mole - this will provide you with a conversion factor. So take the measurement in moles and multiply it by the atomic weight to convert to grams. Really what you're doing is dividing the number by 1 mole, and multiplying it by the equivalent of one mole, the atomic weight. That's the thought process behind unit analysis and how you get your "units to cancel".In this case, the answer is about 882.43 grams Fe.
10 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 1023/1 mole Fe) = 1.1 X 1020 atoms of iron ===================
In the reaction of Fe with H₂O to produce FeO and H₂, the ratio is 3 moles of H₂O for every 1 mole of Fe. Since the molar mass of Fe is 56 g/mol and that of H₂O is 18 g/mol, we use these values to find that 750 grams of Fe will produce 750 * (3 * 18 / 56) = 857.14 grams of H₂O.
