The molarity of pure water at 4 ∘ C is Options: A . &nbsp1 M B . &nbsp2.5 M C . &nbsp5 M D . &nbsp55.5 M

Answer: Option D : D The density of water is 1 g c m − 1 at 4 ∘ C So, molarity= 1000 18 =55.5M.

The molarity of pure water at 4∘C is

Question

The molarity of pure water at

4^{\circ} C

Options:

A . 1 M

B . 2.5 M

C . 5 M

D . 55.5 M

Answer: Option D
:
D
The density of water is

1 g c m^{- 1}

4^{\circ} C

So, molarity=

\frac{1000}{18}

=55.5M.
