How many MOLES of oxygen are present in 6.56E+22 molecules of nitrogen monoxide
How many ATOMS of nitrogen are present in 1.79 moles of nitrogen monoxide ?
1 mole contains 6.02E23; therefore,
mol = 6.56E22/6.02E23 = ?
There are 1.79 x 6.02E23 molecules of NO in l.79 moles and 2 x that number for the numb er of atoms.
To calculate the number of moles of oxygen in a given number of molecules of nitrogen monoxide, we need to use Avogadro's number. Avogadro's number is defined as 6.022 x 10^23 particles per mole.
Step 1: Determine the number of oxygen atoms in one molecule of nitrogen monoxide (NO).
- Nitrogen monoxide (NO) has one nitrogen (N) atom and one oxygen (O) atom.
- Since we're trying to find the number of moles of oxygen, we only need to focus on the oxygen atom.
- Nitrogen monoxide has one oxygen atom per molecule.
Therefore, there is 1 oxygen atom per molecule of nitrogen monoxide (NO).
Step 2: Convert the given number of molecules to moles.
- Given: Number of molecules of nitrogen monoxide = 6.56E+22 molecules.
- Since each molecule of nitrogen monoxide contains 1 oxygen atom, the number of oxygen atoms is also 6.56E+22.
To convert the number of atoms to moles, we divide by Avogadro's number:
Number of moles of oxygen =
(6.56E+22 atoms) / (6.022 x 10^23 atoms/mol)
≈ 0.109 moles of oxygen
Therefore, there are approximately 0.109 moles of oxygen in 6.56E+22 molecules of nitrogen monoxide.
Now, let's calculate the number of nitrogen atoms in a given number of moles of nitrogen monoxide.
Step 1: Determine the molar ratio of nitrogen to nitrogen monoxide (NO).
- The chemical formula for nitrogen monoxide is NO, which means it contains 1 nitrogen atom.
- Therefore, the molar ratio of nitrogen to nitrogen monoxide is 1:1.
Step 2: Use the given number of moles to calculate the number of nitrogen atoms.
- Given: Number of moles of nitrogen monoxide = 1.79 moles.
Number of nitrogen atoms =
(Number of moles) x (Avogadro's number) x (Molar ratio)
= (1.79 moles) x (6.022 x 10^23 atoms/mol) x (1)
≈ 1.08 x 10^24 atoms
Therefore, there are approximately 1.08 x 10^24 nitrogen atoms in 1.79 moles of nitrogen monoxide (NO).
