Question: What is the mass of 5 moles of iron III oxide?

What is the mass of 5 moles of iron?

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

What is the mass of 5 moles?

The mass of 1 mole of any substance is equal to that substance’s molecular weight. Thus we can say that each mole of $S{O_2} $ weighs 64 grams. Therefore the mass of 5 moles of $S{O_2} $ is 320 grams.

What is the mass of 2.00 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).

How do you find the mass of a mole of iron?

We simply divide the five grams by the molar mass of iron. Molar mass is defined as the number of grams in one mole of a given element. Iron has a molar mass of 55.84 grams/mole. So, five grams divided by 55.84 grams/mole gives us 0.089 moles of iron.

How many grams is 5 moles of CL?

5.720 x 10^-23 grams per atom (notice the negative sign).

How many moles of O are in 1 mole of Fe2O3?

Unlock

Formally, a mole of X contains 6.02*10^23 units of X. This could be cars, bananas, or parakeets, but usually, it refers to molecules and atoms. For our purposes, the statement that we have 1 mole of Fe2O3 means that we have 6.02*10^23 molecules of Fe2O3. Therefore, our result is 1.806*10^24 atoms of oxygen.
