Calculate the no of neutrons in 18ml of water

1.	Calculate the no of neutrons in 18ml of water
Answer» 18ml of water has 18G weight Number of moles =Mass ÷molecular mass Molecular mass of water is 18. And we have 1 MOLE of water so According to Avogadro number 1 mole contain 6.023×10^23 atoms Hydrogen atom contain 0 neutron And Oxygen contain 8neutron in 1 atom of water so number of neutron required =8×6.023×10^23 =48184×10^20 NEUTRONS

Answer»

18ml of water has 18G weight

Number of moles =Mass ÷molecular mass

Molecular mass of water is 18.

And we have 1 MOLE of water

According to Avogadro number 1 mole contain 6.023×10^23 atoms

Hydrogen atom contain 0 neutron

And

Oxygen contain 8neutron in 1 atom of water

number of neutron required

=8×6.023×10^23

=48184×10^20 NEUTRONS
