The osmotic pressures required for this process can be as high as 20.1 . What would the molar concentration of the tree sap have to be to achieve this pressure on a day when the temperature is 35?
Diamonds are measured in carats where 1 carat= 0.200 g. The density of diamond is 3.51 g/cm^3. What is the volume of a 2.50-carat diamond
How many grams of CaH2 are needed to generate 145 liters of H2 gas if the pressure of H2 is 825 torr at 21 C.

how many grams of coniine would he have needed to ingest to give a 50% chance of causing his death? If Coniine is about 3.2% by weight of the hemlock leaves, how many grams of hemlock would need to be used to make the tea?
The effective nuclear charge, Zeff, for a valence electron can be approximated using the "core charge" of the atom, that is, the total charge of the nucleus and the inner (non-valence) electrons.
