Question

how many molecules of water are present in 36g of water (H=1, O=16)​

Answer 1

Answer:

12.044 $X 10^{10}$

Explanation:

It is 2 moles.

Answer 2

Explanation:

The chemical formula of water is H2O

So 2×1+16=18 gm of water contains 1mole of molecules i.e. 6.023×10²³

So the number of molecules in 36 gm of water

=2×number of molecules in 18 gm of water

=2×6.023×10²³=12.046×10²³.(answer)
