# of moles = Mass÷ Formula weight
Example:
6 grams of Carbon atoms
Carbon has an Atomic Mass of 12 grams so according to the Equation
# of moles = 6÷ 12 = 0.5 moles
For a compound such as CO2 , Formula weight = ( 1 mole of carbon atom weighs 12 grams + 2 moles of oxygen atoms weighs 32 grams ) 44 grams.
Example: 24 grams of carbon dioxide = 24÷ 44 = 0.5454 moles
So for sodium, # of moles = 45.48 g ÷ 22.99g/mole = moles
You divide!
12 right?
divide by Avogadro's number to get 0.090 mole
The answer is 9,92 moles.
Sodium Carbonate + Sulfuric acid ------> Sodium Sulfate + Water + Carbon Dioxide Na2CO3 + H2SO4 ------> Na2SO4 + H2O + CO2 1 : 1 : 1 : 1 : 1 1 mole of na2co3 will react with h2so4
8,75 moles of oxygen are needed.
There would be 0.1 moles of NaCl present in 1 liter of a 0.1M solution of sodium chloride. This is based on the definition of molarity which is moles of solute per liter of solution.
12 right?
5.27 mol
divide by Avogadro's number to get 0.090 mole
you would get 6.4 mols of NaCl and 0.3 mols of unreacted Na
The answer is 9,92 moles.
49.03924
I suppose that the answers are: - 0,9 moles aluminium ions - 2,7 moles chloride ions
