Al(NO3)3 has 9 atoms of oxygen.
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.
14.0 g x 1 mole/187.56 g = 0.0746 moles0.0746 moles Cu(NO3)2 x 6 moles O/mole Cu(NO3)2 = 0.448 moles O atoms0.448 moles O atoms x 6.02x10^23 atoms/mole = 2.70x10^23 atoms of oxygen
its Al + NO3 + NO3 + NO3. So one Al, three N and nine O. That makes 13 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.)
Al(NO3)3 has 9 atoms of oxygen.
In each molecule of NO3, there is one nitrogen atom and there are three oxygen atoms.
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 3 atoms bro. NO3 means 3 atoms of oxygen. NO2 means 2 atoms of oxygen. NO means 1 atom of oxygen.
Copper nitrate has six atoms of oxygen.
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.
Barium nitrate has 6 oxygen atoms.
One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
2 KNO3 has 6 oxygen atoms.
There is no such compound as BaNO3. The correct formula for barium nitrate is Ba(NO3)2 and in this case, each formula unit would have 6 x 6.02x10^23 atoms of oxygen
One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
Copper(II) nitrate has six oxygen atoms.
