Question

Calculate the total number of atoms in 3.6 gm of water.​

Answer 1

Answer:

gram molecular mass of water=1×2+16=2+16=18g

18g of water=6.022×10^23 atoms

1g of water=6.022×10^23/18

3.6 g 0f water=6.022×10^23×3.6/18

=21.679×10^23/18

=1.204×10^23 atoms

Answer 2

Answer:

1.2044 gms.

Explanation:

gram molecular mass of water is 18.

so, in 18 grams of water = 6.022 gms.

1 ,, ,, ,, = 6.022/18 gms.

3.6 ,, ,, ,, = (6.022x3.6)/18 gms.

or, 21.6792/18 gms

or, 1.2044 gms.
