Analysis of Concentration of Sulphuric Acid in Bottles A and B
Definition of Concentration
Concentration refers to the amount of solute in a given volume of solution. It is usually measured in molarity (M) which is defined as the number of moles of solute per liter of solution.
Determination of Concentration of Sulphuric Acid in Bottles A and B
To determine the concentration of sulphuric acid in bottles A and B, we need to use the formula:
Molarity = (mass of solute in grams) / (molecular weight of solute x volume of solution in liters)
Given that the density of the solution is 1g/ml, we can assume that the volume of solution is equal to the mass of solution in grams.
Therefore, the concentration of sulphuric acid in bottle A is:
Molarity = (1 mol / 98 g) x 1000 g = 10.2 M
And the concentration of sulphuric acid in bottle B is:
Molarity = (1 mol / 98 g) x 1 g = 0.01 M
Comparison of Concentration of Sulphuric Acid in Bottles A and B
Comparing the concentrations of sulphuric acid in bottles A and B, we can conclude that:
A) A is more concentrated than BThis is because the molarity of sulphuric acid in bottle A is 10.2 M which is much higher than the molarity of sulphuric acid in bottle B which is only 0.01 M.
Therefore, we can say that bottle A contains a more concentrated solution of sulphuric acid than bottle B.
