How many moles in 1.25 grams of iron nitrate?
To find the number of moles in 1.25 grams of iron nitrate, we need to know its molar mass. Iron nitrate has a molar mass of approximately 404.0 g/mol. By dividing the mass by the molar mass, we find that 1.25 grams of iron nitrate is roughly 0.0031 moles.
If 5.58 g of iron react with sulfur to produce 8.79 g of iron sulfide what is the mass of reacting sulfur?
To find the mass of reacting sulfur, we can use the law of conservation of mass, which states that the mass of the reactants equals the mass of the products. Here, the mass of iron sulfide produced (8.79 g) is the sum of the mass of iron (5.58 g) and the mass of sulfur. Thus, the mass of sulfur can be calculated as: Mass of sulfur = Mass of iron sulfide - Mass of iron Mass of sulfur = 8.79 g - 5.58 g = 3.21 g. Therefore, the mass of reacting sulfur is 3.21 g.
What is the mass of 2.38 mole of the element iron?
The molar mass of iron is 55.85 g/mol. To find the mass of 2.38 moles of iron, you would multiply the number of moles by the molar mass: 2.38 mol * 55.85 g/mol = 133.03 g. Therefore, the mass of 2.38 moles of iron is 133.03 grams.
How do you find the theoretical mass of iron in one serving of cereal?
To find the theoretical mass of iron in one serving of cereal, you first need to check the nutritional label for the iron content per serving, usually listed in milligrams (mg). Then, convert this amount to grams by dividing by 1,000, as there are 1,000 mg in a gram. If the iron is in a compound form (like ferrous sulfate), you may need to calculate the specific mass of iron based on the molar mass of the compound and the proportion of iron in it. Finally, use this information to express the theoretical mass of iron in grams.
How do you find the density of iron if Cm has a mass of g?
It is g units [of mass] per cubic metre.
What mass of iron is contained in 86.6 grams of chalcopyrite?
To calculate the mass of iron in chalcopyrite (CuFeS2), we need to find the atomic mass of iron and the chemical formula weight of chalcopyrite. Iron has an atomic mass of 55.85 g/mol, and the formula weight of chalcopyrite is 183.54 g/mol. The mass percentage of iron in chalcopyrite is calculated by (55.85 / 183.54) x 100 = 30.45%. Therefore, the mass of iron in 86.6 grams of chalcopyrite can be found by multiplying 86.6 g by 0.3045 to get 26.34 grams of iron.
How much does iron weigh?
A single iron atom weighs 55.845 atomic mass units.The weight of a quantity of pure iron will vary depending on the volume and gravitational acceleration. The mass of iron will also vary depending on the given volume. Given the density at room temperature, 7.874 g·cm−3 and the volume of iron, you can find the mass by multiply the density and the volume. To find the weight of an object, you would need to multiply its mass by the local gravitational acceleration.
How many grams of iron are contained in 34 grams of fe2s3?
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.
How calculate the mass of iron 2 sulfate?
To calculate the mass of iron (II) sulfate (FeSO4), you would first find the atomic mass of each element (iron, sulfur, and oxygen) using the periodic table. Then, add the atomic masses of each element (Fe + S + 4O) to find the molar mass of FeSO4, which is approximately 151.91 g/mol. Finally, you can then calculate the mass of FeSO4 by multiplying the molar mass by the number of moles.
What mass of iron is contained in 86.6 grams of CuFeS2?
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.
What is the atomic mass of iron?
The atomic mass of iron is approximately 55.85 atomic mass units.
