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 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.
What is the atomic mass of Fe?
The atomic mass of iron (Fe) is approximately 55.85 grams per mole.
What is the mass in grams of 25 mol of sodium hydroxide?
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams/mol. To find the mass of 25 moles of NaOH, you would multiply the number of moles by the molar mass: 25 mol * 40 g/mol = 1000 grams. So, the mass of 25 moles of sodium hydroxide is 1000 grams.

What is the percent of iron in iron (II) hydroxide?
Iron (II) hydroxide has a chemical formula Fe(OH)2. To find the percent of iron in iron (II) hydroxide, you need to calculate the molar mass of iron (Fe) and divide it by the molar mass of the compound Fe(OH)2, then multiply by 100 to get the percentage. The percent of iron in iron (II) hydroxide is approximately 69.9%.
How many grams of aluminum hydroxide are obtained from 17.2 grams of aluminum sulfide?
To determine the grams of aluminum hydroxide obtained from 17.2 grams of aluminum sulfide, we need to consider the stoichiometry of the reaction between aluminum sulfide and water to form aluminum hydroxide. Given the balanced chemical equation, we can calculate the molar mass of aluminum hydroxide and use it to convert the mass of aluminum sulfide to grams of aluminum hydroxide formed.
