Dissolve one of the following in 1 L of distilled water:
480 g MnSO4 • 4H2O -or-
400 g MnSO4 • 2H2O -or-
364 g MnSO4 • H2O
Basically.. You have to look at the periodic table and check it all up but the answer is feso4

Ruth would know that some of the copper sulphate crystals had dissolved in the water by observing if the water changed color to blue, which indicates that the copper sulphate dissolved. Additionally, she could check if there are fewer crystals at the bottom of the container, as they would have dissolved into the water. Ruth can also test by inserting a clean spoon and checking if any more crystals can stick to it, indicating that some have dissolved.
