Question

Calculate the no. of neutron in 54 mL H20 at 27°C & 1 atm.​

Answer 1

Explanation:

Molecular weight of H

2

O=18g

No. of neutrons in 1 mole i.e. 18g of H

2

O=8N

A

( from O atom, as H has no neutron)

Given moles of H

2

O=

18

54

=3

∴ Total no. of neutrons present =3×8N

A

=24N
