43.7g of anhydrous CuSO4 were dissolved in water and the solution made up to 2dm^3. What is the minority of the solution

Answer 1

To determine the minority of the solution, we need to know the concentration of the solution.

First, we need to calculate the molar mass of anhydrous CuSO4:

CuSO4 = (1 x 63.55 g/mol) + (1 x 32.07 g/mol) + (4 x 15.99 g/mol)
CuSO4 = 159.61 g/mol

Next, we need to calculate the number of moles of CuSO4 present in the solution:

moles = mass/molar mass
moles = 43.7 g / 159.61 g/mol
moles = 0.274 moles

Finally, we can calculate the concentration of the solution (in mol/dm^3 or M):

concentration = moles/volume
concentration = 0.274 mol / 2 dm^3
concentration = 0.137 M

Therefore, the minority of the solution is 0.137 M.
