The molarity of pure water is

A

18

B

50

C

55.6

D

100

Text Solution

Verified by Experts

The correct Answer is:
C
Mass of 1 L or 1000 ml water =` 1000 ml xx 1 g mL^(-1)`
(Density of water at `4^@C` ) = 1000 g
Number of moles of water in its 1L ` = (1000g)/(18g "mol"^(-1)) = 55.55 `mol.
Hence, molarity of pure water is 56.6.
