Sludge is when we are going to have a container of materials mix together and we have to pull it out and find out what the material is.

Volume is Length times width times height. you can also do it by putting it in water and taking the amount of water you started with and how much it rises and subtract them and that is you volume. Always use units. CM^3 or ML.

Always be precise and go to the tenths place. The smaller graduated cylinder measures by .2 for each line and the big graduated cylinder measures by 1 for each line. You just have to be very careful and precise.

You have to take the mass and divide it by the volume you got. It is d=m/v. The unit is grams per CM^3. Same for liquids. You take the mass and divide it by the volume.

you need mass of graduated cylinder. You also need mass of graduated cylinder and the liquid. Then you would subtracted them and then you would have the mass of the liquid. Then you need to find the volume and last dived mass by the volume.

# data[].attributes.body
It is the opposite of the liquid density you need the volume of the water volume of the water and the object. Then you subtract and get the volume of the object. Then you need the mass of the object. Then you will dived the mass and the volume of the object to get the density

it will dissolve  faster if you heat, stir crush the solute. soulte is the substance that can dissolve. solvent is the water of alcohol what ever it dissolved in. Aqueous is seeing if it dissolves in water and tincture is if it dissolves in alcohol solubility is when it has dissolved the maximum amount of solute. you can test this by stirring it for a couple minutes and once that is do you will poor out the water without getting the excess solute in the evaporating dish. Then you would boil off the water and then weigh the the solute that dissolve and you would subtract it from the empty watch glass and the cup to get the mass of it.

Make sure that you use boiling chips. when it starts to plateau change out test tube. and once temp start to go up for the second time you you switch the test tube again. If it starts to bubble to high take the bunsen burner off for a minute.  don't let the liquid get above 105 in temp. make sure you have at least 5 ML. make sure that the plateau is within one degree and it has to do it 3 to 5 times. Do not let the distillation tube touch the bottom of the test tube or the water. Use striker to hold tube and hose in water so it does not fall out. Full up the water in the beaker to about 550ML.
