A mole of an element is X grams of the element, where X is the number of the elements atomic mass.
The atomic mass of iron is 55.85, so one mole of iron is 55.87 grams.
Two moles of iron is 111.7 grams.
101.7 grams is 101.7/55.85 moles = 1.82 moles.
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
The answer is 0,2686 moles.
1.68 grams iron (1 mole Fe/55.85 grams) = 0.030 moles iron ==============
111.8g/55.8g= 2.004 moles
23 grams iron ( 1mole Fe/55.85 grams) = 0.41 moles of iron
8200 grams iron (1 mole Fe/55.85 grams) = 146.8 moles iron ============
To calculate the number of moles from grams, you must divide by the substance's molar mass
1,25 g of anhydrous iron(III) nitrate = 0,005 moles
75.89 grams of FeO is equal to 1.06 moles of iron II oxide. In decomposition, there would be 1.06 moles of iron recovered, or 58.99 grams.
2 moles of iron is equal to 111,69 g.
The rusting of iron has the reaction 4 Fe + 3 O2 equals 2 Fe2O3. So every 2 moles of iron produces 1 moles of iron oxide. 16.7 grams is .299 moles of iron. This means there are 0.149 moles of iron oxide or 23.88 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.
150.0 grams Fe2O3 (1 mole Fe2O3/159.7 grams) = 0.9393 moles or iron(III)oxide
16 grams of oxygen how many moles is 0,5 moles.
The answer is 2,507 moles iron.
Find iron (Fe) on the periodic table the biggest number (at the bottom) is the mass number 1 mole is that number in grams. you can work it out from there.
25 grams Fe2O3 (1 mole Fe2O3/159.7 grams) = 0.16 moles iron (III) oxide ( Ferric oxide ) ==============================
