You must do a much better job of explaining what experiment you are doing and the procedure for same.
OK this lab is on the formula of a precipitate and there were 8 test tubes of precipitate prepared obtaining different masses... but why does different masses of precipitate were obtained only for test tube IV and V?
What was in test tube IV and how much? What was in test tube V and how much? What was added to tt IV? What was added to tt V? How much was added to each?
We have no idea what your are doing if you don't tell us.
