A sample of nitric acid contains 50 HNO3 molecules How many oxygen atoms are in this sample?
In each nitric acid molecule (HNO3), there is one oxygen atom. So, in a sample containing 50 HNO3 molecules, there would be 50 oxygen atoms.
HNO3 is an example of a mixture or a solution?
HNO3 is not an example of a mixture. It is a solution of nitric acid in water where the nitric acid molecules are completely dissolved in water molecules.
How many atoms are there in the compound 4 HNO3?
HNO3 is consist of 1 hydrogen atom, 1 nitrogen ato and 3 oxygen atoms. That means there are 5 atoms in 1 HNO3. So there are 20 atoms in 4 HNO3.
How many oxygen atoms in 30 HNo3 molecules?
In every molecule of HNO3 there are 3 oxygens and you have 30 molecules so multiply 30 X 3 = 90 oxygen atoms in 30 molecules of nitric acid.
How many oxygen atoms are there in the molecule HNO3?
There are three oxygen atoms in the molecule HNO3.

How many moles of molecules are there in 250g of hydrogen nitrate?
To find the number of moles in 250g of hydrogen nitrate (HNO3), we first need to determine the molar mass of HNO3. The molar mass of HNO3 is 63.01 g/mol. Then, we can calculate the number of moles by dividing the given mass by the molar mass: 250g / 63.01 g/mol = approximately 3.97 moles of HNO3 molecules.
How many oxygen atoms are there in the molecule HNO3?
There are three oxygen atoms in the molecule HNO3.

What are two examples of polyatomic molecules?
Examples: HNO3, U3O8, K2SO4, NH4Cl, Al(OH)3 etc.
How many valence electrons does HNO3 have?

How do you balance N2O5 plus H2O yields HNO3?
N2O5 + H2O == HNO3 + HNO3 Usually written as N2O5 + H2O = 2HNO3 You have 2 x nitrogen in N2O5 , so 2 x nitrogen in the products, one each in the two molecules of nitric acid. You have 2 x hydrogen in H2O , so 2 x hydrogen in the products, one each in the two molecules of nitric acid. You have 5 oxygens in N2O5 + 1 oxygen in water making for 6 oxygens. These oxygen are equally shared ( 3 each) in the two nitric acid molecules. However, we do not write ' HNO3 + HNO3 ' in chemistry , but use a little bit of 'shorthand' and write it as ' 2HNO3 '. to indicate that there are two(2) molecules of nitric acid formed.
How many resonance structures are needed to describe the structure of HNO3?
To describe the structure of HNO3, two resonance structures are needed.
How many millimoles of HNO3 are present at the start of a titration?
The number of millimoles of HNO3 present at the start of a titration will depend on the initial concentration and volume of the HNO3 solution. To calculate millimoles, you can multiply the concentration of HNO3 in moles per liter by the volume of the solution in liters.
