Answer:
Molarity is defined as the number of moles of the solute per litre of solution.
Molarity=
Volume of solution in litre
No of moles of solute
We are given that the density of water is 1g/ml. This is equal to $$ 1 Kg/ L $$.
Therefore, the mass of 1L of water will be:
= Density of water × Volume
=1
L
Kg
×1L
=1Kg
=1000g
Therefore, number of moles in 1Kg of water =
molarmass
mass
=
18
1000
=55.56
Therefore, molarity of water = =
1L
55.56moles
=55.56 M
