The number of moles is 0,4375.
8,75 moles of oxygen are needed.
12 right?
The number of water molecules obtained is 120,44281714.10e23.
divide by Avogadro's number to get 0.090 mole
The answer is 9,92 moles.
8,75 moles of oxygen are needed.
12 right?
Any
using Avagadro's number you can go from a number of something to mols, or you can go backwards, from mols of something to particles/atoms/molecules etc.
1 mol of oxygen is 16.00g. Therefore 2.43g of oxygen would contain 0.152 mols of oxygen. (2.43g/16.00g)
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
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
you would get 6.4 mols of NaCl and 0.3 mols of unreacted Na
Exactly the same number of mols. 1 mol of oxigen atoms produces 1 mol of water molecules.
The water molecule is made up of 2 atoms of Hydrogen and one atom of Oxygen. So a total of 3 atoms. For other measurements, google Avogadro, mols, etc.
Mols-Linien was created in 1964.
