Question

c. A given packaged bottle of water contains one litre of water. The number of moles of water present in this
quantity of water will be (Given: density of water is 1 g/mL)
1. 52.56.
ii. 53.56.
ii. 54.56.
iv. 55.56.​

Answer 1

Answer:

Option D.

Explanation:

We know that density of water 1  

mL  gm

​Given volume of water =1000 mL

mass of water (given) =1000×1=1000 gm

∴  Moles =  18

1000 =55.55

∴   No. of molecules =55.55 N  A

​  

Answer 2

Answer:

iv. 55.56

Explanation:

We know that density of water 1  

mL

gm

Given volume of water =1000 mL

mass of water (given) =1000×1=1000 gm

∴  Moles =  

18

1000

=55.55

∴   No. of molecules =55.55 N
