12 right?
8,75 moles of oxygen are needed.
The number of moles is 0,4375.
The answer is 9,92 moles.
The number of water molecules obtained is 120,44281714.10e23.
divide by Avogadro's number to get 0.090 mole
8,75 moles of oxygen are needed.
5.27 mol
1 mol of oxygen is 16.00g. Therefore 2.43g of oxygen would contain 0.152 mols of oxygen. (2.43g/16.00g)
The number of moles is 0,4375.
Any
I have already balanced - 2C2H2+5O2->4CO2+2H2O what do I do next? 2 moles acetylene--------------5 moles oxygen O2 7 moles acetylene--------------x moles oxygen O2 x = 7 x 5/2 = 17,5
As oxygen is a diatomic gas it would take 6000 moles. As oxygen gas is 32 g/mole this would be 192000 grams or 192kg. At STP this would be a volume of (1)V =6000R(273) P=1atm R=8.314 v=13,618,332m3
you would get 6.4 mols of NaCl and 0.3 mols of unreacted Na
The answer is 9,92 moles.

I suppose that the answers are: - 0,9 moles aluminium ions - 2,7 moles chloride ions
