. What is the mass concentration (titer) is a solution of sulfuric acid with the molar concentration equivalent
0.5 mol/dm3?
To determine the mass concentration (titer) of a solution, we need two pieces of information: the molar concentration and the molar mass of the solute.
In this case, the molar concentration is given as 0.5 mol/dm^3 (or 0.5 M). This means that for every 1 liter (dm^3) of solution, there are 0.5 moles of sulfuric acid.
The next step is to find the molar mass of sulfuric acid (H2SO4). The molar mass can be calculated by adding up the atomic masses of all the elements in the chemical formula.
H (hydrogen) has an atomic mass of approximately 1 g/mol.
S (sulfur) has an atomic mass of approximately 32 g/mol.
O (oxygen) has an atomic mass of approximately 16 g/mol.
Since there are 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms in sulfuric acid, we can calculate the molar mass as follows:
(2 * 1 g/mol) + (1 * 32 g/mol) + (4 * 16 g/mol) = 98 g/mol
So, the molar mass of sulfuric acid is approximately 98 g/mol.
Now we can calculate the mass concentration using the formula:
Mass Concentration (titer) = Molar Concentration * Molar Mass
Mass Concentration (titer) = 0.5 mol/dm^3 * 98 g/mol
Mass Concentration (titer) = 49 g/dm^3
Therefore, the mass concentration (titer) of the solution of sulfuric acid with a molar concentration of 0.5 mol/dm^3 is 49 g/dm^3.
