Water has a molecular weight of 18. A milliliter of liquid water has a mass of one gram. Calculate the molar concentration of liquid water:
Solution
Mole is a unit of measurement used to express amounts of a chemical substance. The concentration of a solution is mostly expressed by its molarity, which is the number of moles of the dissolved substance per litre of solution.
Molarity (M) = weight/molecular weight * volume/1000
The molar concentration of liquid water is = weight/molecular weight * 1000/1
Molar concentration of liquid water is = 1g/18* 1000 = 55.5 M
