A column is filled with four different liquids of different densities. A red liquid, a blue liquid, a green liquid, and a purple liquid are all added into the column. This chart shows the densities of the liquids. A 2-column table with 4 rows titled densities of liquids. The first column titled Liquids has entries red, blue, green, purple The second column has entries 1.2 grams per centimeter cubed, 1.6 grams per centimeter cubed, 0.8 grams per centimeter cubed, 0.1 grams per centimeter cubed.

In what order would the liquids would arrange themselves, from top to bottom?

blue, red, purple, green.
purple, green, red, blue.
purple, green, blue, red.
blue, red, green, purple.

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)
