There are 9 atoms of oxygen in one formula unit of aluminum nitrate (Al(NO3)3).
The compound copper nitrate has Cu(NO3)2 for a chemical formula. In that formula, we see that there is an NO3 radical present, and that there are 3 atoms of oxygen in that radical (the sub 3 after the O). But there are 2 of those NO3 radicals (the sub 2 outside of the parens) present in this compound. That means that there are 3 x 2 oxygen atoms in a molecule of copper nitrate, or 6 atoms of oxygen in Cu(NO3)2.
There are a total of 27 atoms in 3Cu(NO3)2. This includes 3 copper (Cu) atoms, 6 nitrogen (N) atoms, and 18 oxygen (O) atoms.
There are a total of 19 atoms in one molecule of Al(NO3)3. This includes one aluminum atom, three nitrogen atoms, and nine oxygen atoms.
The formula unit Ba(NO3)2 contains 6 oxygen atoms. (Multiply the subscript 3 in the nitrate ion by the subscript 2 after the parentheses close.)
A nitrate is represented by -NO3 whereas a nitrite is represented by -NO2. So to answer your question, nitrates have 1 oxygen atom more than nitrites.
There are 9 atoms of oxygen in one formula unit of aluminum nitrate (Al(NO3)3).
Ba(NO3)2 contains a total of 6 oxygen atoms - there are 3 oxygen atoms in each nitrate (NO3) group, and there are 2 nitrate groups in Ba(NO3)2.
In each molecule of NO3, there is one nitrogen atom and there are three oxygen atoms.
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.
Copper nitrate has six atoms of oxygen.
The compound Ba(NO3)2 contains a total of 6 oxygen atoms. This is because each nitrate ion (NO3-) has one nitrogen atom and three oxygen atoms, and there are two nitrate ions in Ba(NO3)2.
One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
The compound copper nitrate has Cu(NO3)2 for a chemical formula. In that formula, we see that there is an NO3 radical present, and that there are 3 atoms of oxygen in that radical (the sub 3 after the O). But there are 2 of those NO3 radicals (the sub 2 outside of the parens) present in this compound. That means that there are 3 x 2 oxygen atoms in a molecule of copper nitrate, or 6 atoms of oxygen in Cu(NO3)2.
There are a total of 27 atoms in 3Cu(NO3)2. This includes 3 copper (Cu) atoms, 6 nitrogen (N) atoms, and 18 oxygen (O) atoms.
There are a total of 19 atoms in one molecule of Al(NO3)3. This includes one aluminum atom, three nitrogen atoms, and nine oxygen atoms.
The formula for aluminum nitrate is Al(NO3)3, so there are 9 oxygen atoms. Multiply the number of oxygen atoms inside the parentheses times the subscript outside the parentheses.
