The number of atoms is 18,066.10e23.
The total number of atoms in one molecule of Al2(CO3)3 is 14.
To calculate the number of oxygen atoms in 2 NO3 molecules, you first need to determine the total number of oxygen atoms in one molecule of NO3, which is 3 oxygen atoms. Since you have 2 NO3 molecules, you would multiply the number of oxygen atoms in one molecule by the number of molecules, giving you a total of 6 oxygen atoms.
Heptane has a chemical formula of C7H16. To calculate the number of atoms in heptane, add the number of carbon atoms (7) to the number of hydrogen atoms (16), resulting in a total of 23 atoms in heptane.

The oxide Fe2O3 has 3 oxygen atoms in the molecule.
2,760 atoms.
The total number of atoms in one molecule of Al2(CO3)3 is 14.
There are 9 atoms in C3H6: 3 carbon atoms and 6 hydrogen atoms.
The number of hydrogen atoms is 14,290540253661.10e23.
To calculate the number of oxygen atoms in 2 NO3 molecules, you first need to determine the total number of oxygen atoms in one molecule of NO3, which is 3 oxygen atoms. Since you have 2 NO3 molecules, you would multiply the number of oxygen atoms in one molecule by the number of molecules, giving you a total of 6 oxygen atoms.
Heptane has a chemical formula of C7H16. To calculate the number of atoms in heptane, add the number of carbon atoms (7) to the number of hydrogen atoms (16), resulting in a total of 23 atoms in heptane.
There are a total of 13 atoms in 3CaCl2: 3 calcium atoms and 6 chlorine atoms.
An unbranched alkene with 3 carbon atoms and one double bond will have a chemical formula of C₃H₆. Since each carbon atom forms 4 bonds (including the double bond), we can calculate the number of hydrogen atoms by subtracting the number of carbon atoms (3) from the total number of atoms (6), which gives us 3 hydrogen atoms.
