Question

What is the total number of neutrons present in 54 ml h2o?

Answer 1

18ml=18gm=1mole=Na molecules
54ml= 3 moles
1 mol= 2 atom H+1 atom O
H= 0 neutrons
O= 8 neutrons
total neutrons in 1 molecule water=8 neutrons
3 moles water contains 24Na neutrons

Answer 2

According to scientific research ,we came to know that 18ml or 18gm of water (H2O) means 1 mole of water.

Similarly,

18ml = 1 mole of water.

54 ml = 3 moles of water.

Now,there are always 8 Neutrons in a single mole of water.

So number of neutrons in 3 moles of water will be;

=8×3

= 24 (answer)
