You need the unit of g however you must convert to moles before you can use the mole ratio to find the moles of iron, you used the molar mass of iron to find the grams of iron. since F e 2 o 3
Answer:
if you mutliply 8x2 it would be 16 and half of 16 is 8 and if you multiply that by 2 you get 16 again and then if you multiply that by 2 it comes out to 32 then devide that by 2 and you get 16 then divide again and you get 8
Explanation:
Assuming that the space within the solid or liquid is vacuum, it is not matter because there is no mass inside. However, there is a volume. The volume inside a solid would have regular straight sides because atoms of a solid is compactly arranged. For liquids, the space could be irregular curves and paths because the atoms in a liquid are free-flowing.
Moles of Oxygen they took in : C. 2.42
<h3>Further explanation</h3>
The gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08205 l.atm / mol K
T = temperature, Kelvin
P=1000 kPa
V = 6 L
T = 298 K
moles of Oxygen :
