Read the formula :-
K=1
N=1
O=3
Total = 5
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!
Since the product, K2SO4 has twice as many potassium atoms as the reactant, KNO3, we may conclude that it takes two moles of reactant to produce one mole of product. The sulfate and nitrate ions will not be the limiting factor.
The number of hydrogen atoms in a molecule depends on its chemical structure and formula. For example, in water (H₂O), there are two hydrogen atoms per molecule, while in methane (CH₄), there are four hydrogen atoms. Each unique compound will have a specific number of hydrogen atoms based on its molecular formula.
The molecular weight of potassium nitrate (KNO3) is 101.1 grams/mole.K = 39.1 + N = 14.0 + O = 3*16.0 = 101.1Now divide 6.5 by 101.1 to calculate # of moles => 0.064 moles KNO3

It tells you how many atoms of an element there are in a molocule.
One molecule of KNO4 contains a total of six atoms. 1 Potassium (K), 1 Nitrogen (N) and 4 Oxygen (O).

4, as indicated by the subscript on the symbol for hydrogen in the formula for methane, CH4.
One mole of KNO3 contains 4 potassium atoms, 4 nitrogen atoms, and 12 oxygen atoms, giving a total of 20 atoms.
2 KNO3 has 6 oxygen atoms.
There are no theoretical limits. The number can be as small as one or very large. Likewise the number of atoms in a molecule can be extremely large.
There's only 1 because the N does not have a subscript stating otherwise!

The chemical formula for potassium nitrate is KNO3, which means that one molecule contains five atoms. Therefore, four molecules of potassium nitrate would contain 20 atoms.
To calculate the number of atoms in 3 moles of potassium nitrate (KNO3), you use Avogadro's number, which is 6.022 x 10^23 atoms/mol. First, calculate the molar mass of KNO3 (101.1 g/mol) then multiply that by 3 to get the total mass in grams. Next, divide the total mass by the molar mass to get the number of moles, and finally multiply the number of moles by Avogadro's number to get the number of atoms. For 3 moles of KNO3, there are approximately 5.4 x 10^24 atoms.
To find the total moles of KNO3 needed, use the formula: moles = molarity x volume (in liters). So, moles = 2.0 mol/L x 1.5 L = 3.0 moles of KNO3. Therefore, 3.0 moles of KNO3 need to be dissolved in water to make 1.5 liters of a 2.0 M solution.
