2.4088x10^24
There are 2 types of atoms. Carbon and the other type is Oxygen. 2 Oxygen atoms are bonded to a single Carbon atom.
Individuals of oxygen are formed in the stratosphere when oxygen molecules that consist of two oxygen atoms are striked by ultraviolet light.
9 moles (there are four oxygen atoms for every mol of BaSO4, so you multiply 2.25 by 4)
You would expect to find nitrogen and oxygen as molecules in the atmosphere, and argon as individual atoms.
The compound is called: magnesium oxide. Therefore, there are magnesium and oxygen atoms in the compound. The ions are: Mg2+ and O2-.
5,26 moles of oxygen contain 31,676.10e23 atoms.
Carbon hydregen & oxygen
No.
There are 2 types of atoms. Carbon and the other type is Oxygen. 2 Oxygen atoms are bonded to a single Carbon atom.
1.10x10^24
Individuals of oxygen are formed in the stratosphere when oxygen molecules that consist of two oxygen atoms are striked by ultraviolet light.
20 x 2 x 6.022x1023 = 2.409x1025 atoms of oxygen
9 moles (there are four oxygen atoms for every mol of BaSO4, so you multiply 2.25 by 4)
One carbon atom and 2 oxygen atoms per molecule.
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.
Ozone, O3
You would expect to find nitrogen and oxygen as molecules in the atmosphere, and argon as individual atoms.
