Final answer:
To find the concentration of the Al₂(SO₄) solution, we need to calculate the number of moles of Al₂(SO₄) and divide it by the volume of the solution. The concentration is 0.7308 mol·dm¯³.
Step-by-step explanation:
To calculate the concentration of the solution, we need to determine the number of moles of Al₂(SO₄) in 500g. We can use the formula:
moles = mass / molar mass
The molar mass of Al₂(SO₄) is 342.15 g/mol.
So, moles = 500g / 342.15 g/mol = 1.4616 mol
To find the concentration, we divide the number of moles by the volume of the solution:
concentration = moles / volume
The volume is given as 2 dm³, which is equivalent to 2000 cm³.
So, concentration = 1.4616 mol / 2000 cm³ = 0.7308 mol·dm¯³
Concentration in chemistry refers to the amount of a substance dissolved or contained within a given volume or mass of another substance. It's a measure of how much of a particular substance is present in a specific amount of a solution, mixture, or system.
