23 grams iron ( 1mole Fe/55.85 grams) = 0.41 moles of iron
1,46 moles of aluminum fluoride contain 35,16848.10e23 atoms.
4,5.10e28 molecules of sodium fluoride NaF are equal to 0,745.10e5 moles.
16 grams of oxygen how many moles is 0,5 moles.
417.2 grams FeCrO4 (1 mole FeCrO4/171.85 grams) = 2.428 moles iron (II) chromate =========================( also known as ferrous chromate )
12.8 grams Calcium fluoride (1 mole CaF2/78.08 grams) = 0.163 moles CaF2
4.5 moles
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
23 grams iron ( 1mole Fe/55.85 grams) = 0.41 moles of iron
How many molecules are in 94 grams of sodium fluoride
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
there are 4.5 moles
388.grams Fe divided by mass of Fe 388.2g/55.85= 6.95moles of Fe
1,46 moles of aluminum fluoride contain 35,16848.10e23 atoms.
The formula mass of sodium fluoride, NaF is 23.0+19.0=42.0 Mass of 4.5mol of NaF = 4.5 x 42.0 = 189g
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.
