3.0
This is a chemical calculation. there are 3.267 moles in this solution.
5,26 moles of oxygen contain 31,676.10e23 atoms.
Two moles of neon contain 12,044281714.10e23 atoms.
382 g Co contain 6,482 moles.
This value is 0,06 moles.
The molar mass of barium sulfate, BaSO4 is 233.4 Amount of BaSO4 = mass of sample / molar mass = 14.2/233.4 = 0.0608mol 0.0608 moles of BaSO4 are conained in a 14.2g pure sample.
To find the moles of oxygen in the compound, first calculate the moles of carbon and hydrogen using their respective molar masses. Then, subtract these totals from the total moles present in the compound to find the moles of oxygen.
0.1868 moles
To find the number of moles from molar mass, divide the mass of the compound by its molar mass. The formula is: Moles = Mass (g) / Molar Mass (g/mol). This will give you the number of moles of the unknown compound.
This is a chemical calculation. there are 3.267 moles in this solution.
5,26 moles of oxygen contain 31,676.10e23 atoms.
Two moles of neon contain 12,044281714.10e23 atoms.
Approx 3.29 moles.
9 moles (there are four oxygen atoms for every mol of BaSO4, so you multiply 2.25 by 4)
0,688 g calcium is equivalent to 0,017 moles.
0,27 moles of calcium contain 10,82 g calcium.
382 g Co contain 6,482 moles.
