Are 3 moles of gold heavier than 10 moles of iron?
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)
What mass of carbon monoxide is needed to produce 143.9g of iron according to Fe2O3 3CO --2 Fe 3CO2?
To find the mass of carbon monoxide needed, we need to use the stoichiometric ratio between iron and carbon monoxide. From the balanced equation, we can see that 3 moles of carbon monoxide produce 2 moles of iron. First, calculate the molar mass of iron (Fe), which is 55.85 g/mol. Next, use the molar ratio between iron and carbon monoxide (2:3) to find the moles of carbon monoxide required. Finally, convert the moles of carbon monoxide to grams using its molar mass (28.01 g/mol).
How many moles are equal to 417.2 g of FeCrO4?
417.2 grams FeCrO4 (1 mole FeCrO4/171.85 grams) = 2.428 moles iron (II) chromate =========================( also known as ferrous chromate )
How many moles of mercury are there in 159 g of mercury?
620 grams mercury (1 mole Hg/200.6 grams) = 3.09 moles Hg
How much is 0.44 grams in moles?
This cannot be answered because it is essential to know what element you're dealing with here. 44.3 grams of iron will contain considerably less atoms than 44.3 of hydrogen. Therefore, the number of moles in 44.3 grams of iron will differ from the number of moles in 44.3 grams of hydrogen.Find the formula weight of the material and multiply by the number of moles:44.3 mole x FW gram/mole = ____ gram...for hydrogen gas (H2) the formula weight is 1.00797 g/mol x 2 = 2.01594 g/mol.44.3 mol x 2.01594 g/mol = 89.3 g
What does 7.4 moles of iron weigh in grams?
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.
How many moles on 738 grams or iron and how many atoms?
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
How many moles are in 1.5 grams of iron?
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.
Are 3 moles of gold heavier than 10 moles of iron?
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)
What is the mass of 4 moles of iron?
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.
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.
How many moles are in 223.2 iron (Fe)?
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.
How many moles are in 8.2 grams?
This cannot be answered because it is essential to know what element you're dealing with here. 8.2 grams of iron will contain considerably less atoms than 8.2 of hydrogen. Therefore, the number of moles in 8.2 grams of iron will differ from the number of moles in 8.2 grams of hydrogen.
How many moles are present in 1.68g of iron?
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.
How many moles grams are in 24.6 moles of 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).

How much does one mole of iron atoms weigh?
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
