Al(NO3)3 contains 9 oxy atoms per formula unit.
4.88x10-3 mol x (6.022x1023form units / mole) x (9 atoms oxy / Form Unit)
= multiply and get the answer
im getting 2.938 x 10^19
The number of hydrogen atoms is twice the number of oxygen atoms. Glucose is C6H12O6, so there are 12 hydrogen atoms for every 6 oxygen atoms in a molecule.
The oxide Fe2O3 has 3 oxygen atoms in the molecule.
No, the chemical formula for water is H2O. This means that for every oxygen atom in the compound, there are two hydrogen atoms. Thus, the number of hydrogen atoms in water is double the number of oxygen atoms.
Oxygen gas (O2) is diatomic, meaning it consists of two oxygen atoms chemically bonded together. Therefore, to determine the number of atoms in oxygen gas, we consider the molecular formula. In one molecule of oxygen gas (O2), there are two oxygen atoms. Avogadro's number (6.022 x 10^23) represents the number of entities (atoms, molecules, etc.) in one mole of a substance. Therefore, in one mole of oxygen gas, there are 2 moles of oxygen atoms, equivalent to approximately 1.204 x 10^24 oxygen atoms.
Three oxygen atoms combine to make ozone
It depends on how many hydrogens are there and how many oxygen atoms there are.
No. The atomic number ( number of atoms) for oxygen is 8. The atomic number for NE (neon) is 10. :)
There are 4 oxygen atoms in two oxygen molecules.
Quite a few! 698 grams Al(NO3)3 (1 mole Al(NO3)3/213.01 grams)(9 moles O/1 mole Al(NO3)3)(6.022 X 1023/1 mole O) = 1.78 X 1025 atoms of oxygen ======================
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.

There are 3 atoms bro. NO3 means 3 atoms of oxygen. NO2 means 2 atoms of oxygen. NO means 1 atom of oxygen.
Ozone has three atoms, oxygen has only two.
well, oxygen atoms have only 2.
