Calculate the no of neutrons present in 12x10^25 atoms of oxygen (8O^17)?

1800NA

In one atom of 8 O 17 nutrons are 9 so in 12×10^25 atoms number of nutrons are

9×12×10^25=1800NA

It may be 3200Na

Since the atomic number of oxygen is =8 and atomic mass be =16yet we have given atomic mass =17. No. Of nuteron =atomic mass -atomicno. Therefore nuteron =17-8=9. Since there are 9nuteron in single atom of oxygen so12*10to the power 25atom=12*10to power 25*9=108*10to power25or1.08*10to power 27

To calculate the number of neutrons in an atom of oxygen (O^17), you need to know the atomic number and mass number of the isotope.

The atomic number of oxygen is 8, which means it has 8 protons. The mass number of the isotope O^17 is 17, which represents the total number of protons and neutrons.

Since the atomic number represents the number of protons, you can subtract the atomic number from the mass number to find the number of neutrons.

Number of neutrons = mass number - atomic number
Number of neutrons = 17 - 8
Number of neutrons = 9

So, each atom of oxygen-17 (^17O) has 9 neutrons.

Now, to find the total number of neutrons in 12x10^25 atoms of oxygen-17, you can simply multiply the number of neutrons per atom (9) by the total number of atoms (12x10^25).

Total number of neutrons = Number of neutrons per atom x Total number of atoms
Total number of neutrons = 9 x 12x10^25
Total number of neutrons = 108x10^25

Therefore, the total number of neutrons in 12x10^25 atoms of oxygen-17 is 108x10^25.
