The number of moles is 4.
4 moles - APEX
388.grams Fe divided by mass of Fe 388.2g/55.85= 6.95moles of Fe
14.2g Fe2O3 (1mol Fe2O3/159.7g(2mol Fe/1mol Fe2O3) = 0.178 moles Fe
3,80 g Zn have 0,058 moles.
Moles = weight in g / atomic weight. So moles in 24.7 g of Ar = 24.7 / 39.948 = 0.62 moles
233,2 g iron Feis equivalent to 4,176 moles.
250 g iron (III) oxide is equal to 1,565 moles.
4 moles - APEX
1,25 g of anhydrous iron(III) nitrate = 0,005 moles
23 grams iron ( 1mole Fe/55.85 grams) = 0.41 moles of iron
The mass of 1.23 moles of iron is 58,69 g.
There is 1.42 x 10^-2 moles of formula units that are in 5.67 g of iron III sulfate.
620 grams mercury (1 mole Hg/200.6 grams) = 3.09 moles Hg
Molar mass of iron is 56g. Given mass of iron= 112g No. of moles = Given mass/Molar Mass => 112g/56g= 2 moles
The answer is 125,65 g.
388.grams Fe divided by mass of Fe 388.2g/55.85= 6.95moles of Fe
Fe, or iron, has a molar mass of 55.845 grams per mole. This means that 0.2 moles is equal to 11.2 grams of iron.
