What is the chemical 'FE'. Do you mean 'Fe'. If so to answer your question .
The molar mass of iron (Fe) is 55.845
The answer is 125,65 g.
In the reaction of Fe with HβO to produce FeO and Hβ, the ratio is 3 moles of HβO for every 1 mole of Fe. Since the molar mass of Fe is 56 g/mol and that of HβO 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 HβO.
To determine the number of moles in 82.5 grams of iron, you need to divide the given mass by the molar mass of iron, which is approximately 55.85 g/mol. By dividing 82.5 grams by 55.85 g/mol, you would find approximately 1.48 moles of iron.
To find the number of Cl ions in FeCl3, we first need to calculate the molar mass of FeCl3. Iron (Fe) has a molar mass of approximately 55.85 g/mol, and chlorine (Cl) has a molar mass of approximately 35.45 g/mol. Therefore, the molar mass of FeCl3 is 55.85 + (3 * 35.45) = 126.2 g/mol. Next, we determine how many moles of FeCl3 are present in 50.0 g by dividing the mass by the molar mass: 50.0 g / 126.2 g/mol β 0.396 mol. Since there are 3 Cl ions in every FeCl3 molecule, there are approximately 0.396 mol * 3 = 1.19 mol of Cl ions. Finally, we use Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of Cl ions: 1.19 mol * 6.022 x 10^23 Cl molecules/mol = approximately 7.16 x 10^23 Cl ions.
The density of iron is rho = 7,860 kg/m³ or rho = 7.86 g/cm³.
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 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).
To find the number of moles in 23 g of Fe, first find the molar mass of Fe by looking up the atomic weight on the periodic table. Fe has a molar mass of approximately 55.85 g/mol. Divide the given mass by the molar mass to find the number of moles: 23 g Fe / 55.85 g/mol = approximately 0.41 moles of Fe.
The molar mass of Fe(NO3)2 (iron(II) nitrate) is calculated by adding the atomic masses of all the atoms in the formula: Fe (iron) has a molar mass of approximately 55.85 g/mol, N (nitrogen) has a molar mass of approximately 14.01 g/mol, and O (oxygen) has a molar mass of approximately 16.00 g/mol. Therefore, the molar mass of Fe(NO3)2 is around 179.86 g/mol.
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.
To find the mass of iron in CuFeS2, we first calculate the molar mass of CuFeS2: Cu (copper) has a molar mass of 63.5 g/mol, Fe (iron) has a molar mass of 55.8 g/mol, and S (sulfur) has a molar mass of 32 g/mol. Adding these together gives a molar mass of 151.3 g/mol for CuFeS2. Next, calculate the mass percentage of iron in CuFeS2 by dividing the molar mass of iron by the molar mass of CuFeS2 and multiplying by 100. The percentage of iron is approximately 37%, so in 86.6 grams of CuFeS2, the mass of iron would be 0.37 * 86.6 grams = 32 grams.
For this you need the atomic (molecular) mass of FeCl3. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. FeCl3=162.4 grams .200 moles FeCl3
The molar mass of iron (Fe) is approximately 55.85 grams per mole. Therefore, 1 mole of Fe weighs 55.85 grams.
The name is iron(III) nitrate. To calculate the molar mass, we add the molar mass of iron (Fe) and three times the molar mass of nitrate (NO3). The molar mass of iron is approximately 55.85 g/mol, and the molar mass of nitrate is approximately 62.00 g/mol. Therefore, the molar mass of iron(III) nitrate is approximately 208.85 g/mol.
To find the mass of FeO2 for 4.2 moles, you first need to calculate the molar mass of FeO2. Iron (Fe) has a molar mass of 55.85 g/mol, and oxygen (O) has a molar mass of 16.00 g/mol. Adding these together gives a molar mass of FeO2 of 87.85 g/mol. Therefore, the mass of 4.2 moles of FeO2 is 4.2 moles * 87.85 g/mol = 368.37 grams.
The answer is 125,65 g.
To calculate the amount of iron in Fe2S3, first find the molar mass of Fe2S3: Iron (Fe) has a molar mass of 55.85 g/mol and sulfur (S) has a molar mass of 32.06 g/mol. So, the molar mass of Fe2S3 is 2(55.85) + 3(32.06) = 222.92 g/mol. Next, divide the molar mass of iron by the molar mass of Fe2S3 and multiply by the given mass of Fe2S3 to find the grams of iron: (2 * 55.85 g/mol / 222.92 g/mol) * 34 g = 8.53 g of iron in 34 g of Fe2S3.
