There's only 1 because the N does not have a subscript stating otherwise!
The formula for nitrogen is Nā, which means there are 2 nitrogen atoms in each molecule.
Oh, dude, you're hitting me with the chemistry questions, huh? Alright, so in 2 KNO3 molecules, you've got 2 potassium atoms, 2 nitrogen atoms, and 6 oxygen atoms. So, like, in total, you've got 10 atoms in 2 KNO3. Easy peasy, lemon squeezy!
There are a total of 3 nitrogen atoms in the formula Al(NO3)3.
One molecule of KNO4 contains a total of six atoms. 1 Potassium (K), 1 Nitrogen (N) and 4 Oxygen (O).
The chemical formula of ibuprofen isC13H18O2 and there are no nitrogen atoms in it.
One mole of KNO3 contains 4 potassium atoms, 4 nitrogen atoms, and 12 oxygen atoms, giving a total of 20 atoms.
The elemental symbol for nitrogen, N, occurs only once in the formula and it has the subscript 4. This shows that there are four atoms of nitrogen in each molecule of the formula.
KNO3 has 3 elements which are potassium, Nitrogen and Oxygen.
Read the formula :-K=1N=1O=3Total = 5
No: The formula NO shows equal numbers of nitrogen and oxygen atoms in the compound, but the formula NO2 shows twice as many oxygen atoms as nitrogen atoms.

Nine atoms represent the empirical formula of ammonium nitrate. Namely, 2 nitrogen atoms, 3 oxygen atoms and 4 hydrogen atoms.
