What is the mass in grams of 5 02 moles of iron III oxide?

The mass of 5 moles of Fe203 is 798.5 grams.

What is the mass in grams of 2 moles of iron III oxide?

The molar mass of O2 is 2 x 16.00 or 32.00 grams (1 mole O2 = 32.00 grams O2). The mass of a mole of Fe2O3 is (2 x Fe) + (3 x Oxygen) = (2 x 55.845) + (3 x 16.00) = 159.69 grams (1 mole of Fe2O3 = 159.69 grams Fe2O3).

What is the mass of 5.00 moles of iron III oxide?

The mass of 5 moles of Fe203 is 798.5 grams.

What is the mass of O2?

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

How many grams are there in 5 moles of water?

From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water. The molar mass of water is 18 g/mol, so you would end up with 5 x 18 = 90 g of water.

What is the mass of 4.00 moles of Fe?

The mass (m) of Fe is: [55.9 g/mol × 4.50 moles] = 251.6 grams. Note: It is rounded to the nearest one decimal place. 4.50 moles of Fe should give you 251.6 grams of Fe.

How do you find the mass of iron?

Luckily, it’s been done for you! Just find a periodic table, or go to p-table.com. Find iron (“Fe”) and you’ll see a number above it (26) and a number below it (usually) like 55.85. This is both the average mass of an iron atom (in amu) and the molar mass (in g/mol).

What is the mass in grams of 5 moles of Fe?

5 moles of Fe weigh=55.845/1 x 5=279.225g.

How many moles does o have?
