The mass of 1.23 moles of iron is 58,69 g.
The molar mass of iron is 55,845 g.Moles of iron = mass of iron/55,845
To find the number of moles of iron (Fe) in 223.2 g, you can use the formula: moles = mass (g) / molar mass (g/mol). The molar mass of iron is approximately 55.85 g/mol. Thus, moles of iron = 223.2 g / 55.85 g/mol ≈ 3.99 moles.
To determine the mass of Iron, its density is required. The formula used is Volume x Density = Mass. Assuming the Iron is pure and in solid state with a density of approximately 7.87g/cm3 at room temperature, its mass is around 51.2g.
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
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 molar mass of iron is approximately 55.85 g/mol. Thus, the mass of 4 moles of iron would be 4 moles * 55.85 g/mol = 223.4 grams.
To calculate the number of moles in 112 g of iron, divide the given mass (112 g) by the molar mass of iron, which is approximately 55.85 g/mol. So, 112 g / 55.85 g/mol = approximately 2 moles of iron.
The molar mass of iron is 55,845 g.Moles of iron = mass of iron/55,845
The number of moles is 4.
To find the number of moles in 1.5 grams of iron, you need to divide the mass of iron by its molar mass. The molar mass of iron is approximately 55.85 g/mol. So, 1.5 grams of iron is equal to 1.5 g / 55.85 g/mol = 0.027 moles of iron.
To find the number of moles of iron (Fe) in 223.2 g, you can use the formula: moles = mass (g) / molar mass (g/mol). The molar mass of iron is approximately 55.85 g/mol. Thus, moles of iron = 223.2 g / 55.85 g/mol ≈ 3.99 moles.
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.
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.
To calculate the number of moles in 1.68g of iron, we need to use the molar mass of iron, which is approximately 55.85 g/mol. Divide the mass of iron (1.68g) by its molar mass to find the number of moles present. Therefore, there are approximately 0.03 moles of iron in 1.68g.
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 find the number of moles in 233.2 g of iron (Fe), you need to divide the given mass by the molar mass of iron, which is approximately 55.85 g/mol. So, 233.2 g ÷ 55.85 g/mol ≈ 4.17 moles of iron.
To determine the number of moles in 223.2 grams of iron (Fe), you will first need to divide the given mass (223.2 g) by the molar mass of iron, which is approximately 55.85 g/mol. This calculation will give you the number of moles of iron in 223.2 grams.
