Answer to Question #157325 in General Chemistry for MArc

Question

A solution of cupric sulphate is used at blood donor clinics to test donor blood for low iron. Calculate the concentration of this solution, in mol/L, if 125 g of CuSO4 crystals are dissolved in 1.0 L of water

Answer 1

c=n/V

n(CuSO4)=m/M=125/160=0.78mol

c=0.78/1=0.78mol/l

Answer: 0.78 mol/l
