How many grams of copper(II) sulfate pentahydrate (CuSO4 5 H₂O) are needed to prepare 100.00 milliliters of a 0.15 M copper(II) sulfate solution?

How many grams of carbon are in 177.8 mL of a 3.15M solution of octanol(C8H17OH)?|

An aqueous stock sodium bromide solution is prepared by adding 32.1gNaBr to a 50.0mL volumetric flask and filling to the mark with water. How would you prepare 100mL of 0.005MNaBr from this stock solution?

The solubility of N₂ in blood is a serious problem for divers breathing compressed air (78% N₂ by volume) at depths greater than 50 ft (see the margin note, p. 522). (a) What is the molarity of N₂ in blood at 1.00 atm? (b) What is the molarity of N₂ in blood at a depth of 50. ft? (c) Find the volume (in mL) of N₂ , measured at 25°C and 1.00 atm, released per liter of blood when a diver at a depth of 50. ft rises to the surface (kH for N₂ in water at 25°C is 7.0X10⁻⁴ mol/Latm and at 37°C is 6.2X10⁻⁴ mol/L atm; assume dof water is 1.00 g/mL).
