Please if you know help the formula of copper sulfate crystals is CuSo4.5H2O. 400ml of 0.02mol/l copper (ii) sulfate solution is needed to be prepered .
a. calculate the molar mass of the solute .
b. calculate the mass of the solute that sould be weighted to prepare this solution .
c. describe in details the steps of preperation of the solution​

a. 249.5 g/mol

b. 1.996 g

c. Measure 1.996 g of and dissolve in water until the volume is 400 ml

Explanation:

Molar mass is the sum of atomic masses of all the elements present.

Thus molar mass of = 1(63.5)+1(32)+4(16)+5(18) = 249.5 g/mol

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

To calculate the number of moles for given molarity, we use the equation:

c. We need to measure 1.996 g of and dissolve it in water to make the volume 400 ml.
