9 moles (there are four oxygen atoms for every mol of BaSO4, so you multiply 2.25 by 4)
Ba(NO3)2 contains 6 moles of oxygen atoms.
2.25x4 = 9
How many moles of atoms are contained in 382 g Co
0.75 moles of any substance is 0.75(6.02x1023) = 4.52x1023 particles. If those particles are CO2 molecules, and each molecule has 2 oxygen atoms, then it's 2(4.52x1023) = 9.04x1023 oxygen atoms.
Mass of Aluminum Sulfate: 2.74g Molar Mass of Aluminum Sulfate: 342.14 g/mol Therefore, number of moles of Oxygen can be calculated by 2.74g * 12/342.14 g/mol = 0.096 moles Now since u have the moles of Oxygen, the number of oxygen atoms is given by 0.096 mol * (6.02*10^23) particles or atoms/mol that gives u about 5.78 * 10^22 atoms of oxygen
4 moles of oxygen atoms are present in 4 moles of H2O
Diphosphorus pentoxide has 5 oxygen atoms per molecule according to the given prefix. So, 5 moles of it will be 5 x 5 x (6.022x10^23) = 1.51x10^25 oxygen atoms.
5,26 moles of oxygen contain 31,676.10e23 atoms.
How many moles of atoms are contained in 382 g Co

Two moles of neon contain 12,044281714.10e23 atoms.
0.75 moles of any substance is 0.75(6.02x1023) = 4.52x1023 particles. If those particles are CO2 molecules, and each molecule has 2 oxygen atoms, then it's 2(4.52x1023) = 9.04x1023 oxygen atoms.

Diphosphorus pentoxide has 5 oxygen atoms per molecule according to the given prefix. So, 5 moles of it will be 5 x 5 x (6.022x10^23) = 1.51x10^25 oxygen atoms.
10 moles of oxygen atoms or 5 moles of oxygen molecules.
Since there are no subscripts, there is .800 moles of Oxygen atoms and .800 moles of Magnesium because there is .800 moles of the compound.
a. number of atoms = mass / molar mass x avagadros number 21/16x6.02x1023=7.9x1023 atoms b. number of atoms = moles x avagadros number 0.812x6.02x1023=4.89x1023 atoms as there is 1 O atom in each molecule of MgO, there are 4.89x1023 atoms of Oxygen. c. if there are 3.2x1022 molecules and 6 oxygen atoms in each molecule then: (3.2x1022)x6=1.92x1023 Oxygen atoms.
6.00 moles
