6. A 0.4450 g sample of the alloy was transferred into solution and the copper content was analyzed using electrolysis at a current of 0.35 A for 40 min; during this process the mass of the cathode increased by 0.1892 g. Determine whether there was enough time for complete precipitation of Cu if the current efficiency was 90%. Calculate the mass fraction of Cu in the alloy.
