A 1.00 g sample of D2O and H2O are reacted with CL2 and HCL and DCL are produced. Then they are diluted with H2O giving a volume of 1.00L. Then 25 mL of the solution are reacted with excess AgNO3 and 0.3800g AgCl precipitate formed. What was the mass percent of D2O in the original sample of enriched water?
