The concentration of water in such a solution in mol/l is 0.0157 M.
Molar concentration is a measure of the concentration of a chemical species, particularly of a solute in an answer, in phrases of quantity of a substance per unit quantity of solution. In chemistry, the most commonly used unit for molarity is the range of moles consistent with liter, having the unit symbol mol/L or mol/dm³ in the SI unit.
Molarity (M) is the quantity of a substance in a certain volume of solution. Molarity is described as the moles of a solute consistent with liters of an answer. Molarity is likewise called the molar attention of a solution.
Calculation:-
The density of the solution is 1.41 g/mL.
1000 g of the solution will have a volume = Mass/ Density
= 1000 / 1.41
=709 ml.
The mass percent of nitric acid is 70%.
1000 g of the solution will have = 1000× 70/100
=690 g of nitric acid.
The molarity of the solution is = Mass of nitric acid / The molar mass of nitric acid ×Volume of solution.
Mass of nitric acid = 700 / 63×709
= 0.0157 M.
