Ok so I have this procedure to rewrite in past tense passive voice please help me out here I have alot ofthings to do with this lab...your help isgreatly appreciated. Thankyou!

1) Set up a hot-water both by placing th 250/400mL beaker, about two-thirds full of water, on the hot plate. Heat the water to about 85 degrees Celsius.
2) Add about 3g of KCl(s) to a clean, dry test tube and record the actual mass.
3)Add 10.00mL of pure water to the graduated cylinder.
4)Use the plastic pipette to remove 6mL of water from the graduated cylinder. Transfer the water to the test-tube.
5) Insert the thermometer into the test tube and then place the test tube into the hot water bath.
6)Carefully stir the contents of the test tube until the solid had dissolved. Do not leave the test tube in the hot water bath any longer than necessary to dissolve the solid.
7) Remove the test tube from the bath, stir carefully, and record the temperature when the first crystals appear. It may help to hold the test tube up to the lights in the room.
8) Repeat steps 4 to 7 four more times with the same test tube, adding 1.0mL morewater each time (i.e. on the second run you will have 3.0mL of water; 4th run will have 4.0mL water)
9) Empty the contents of the test tube into the waster beaker on the front demo bench.
