Question

Molarity of pure water is
(1) 1 M
(3) 118 M
(2), 1000/18 M
(4) 100/18 M
​

Answer 1

Answer:

Firstly ....

The density of water is...

1g/ml

so..it means...1g water present in 1ml of solution..

convert it in Litre.

so..

1000g present in 1L of solution.bcz molarity always occurs in Litre.

so now , we have volume and wt. of water..

molarity = moles/volume

moles= Wt./M.Wt.

Moles= 1000/18

Molarity=1000/18

bcz volume is 1L

so u can see 3rd option is correct dear
