Question

Find out the total no.of neutrons in 45g of water molecule

Answer 1

⭐⭐⭐ Hey mate!!⭐⭐⭐

__________________________________________________________

❄️45 g of water molecules means

45/18 mole of H2O

❄️As 1mole of H2O contains 6.022×10^23 molecules of H2O

So,

♐Number of molecules in 45/18 mole of H2O =

♐(45/18× 6.022 × 10^23 )

Now,

♐As we know that hydrogen do not contains nutrons...

⚡⚡ So, total number of neutron will be

♐45/18 ×6.022×10^23 × 8

♐= 120.44 ×10^23

♐= 1.2 ×10^25 neutrons

Hope it will help you....✌️✌️
