Two grams of the crystalline compound temperature. At the boiling point temperature of acetone, 100 grams of the same compound dissolve in 100 mL acetone. When recrystallizing 200 g of compound A from acetone, how much solid material can be isolated theoretically after cooling to room temperature when the following volumes of solvent (acetone) are used: a) 100 ml, b) 200 mL, or c) 400 mL

What are the genotypic and phenotypic ratios

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.)
