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).

Citric Acid C6H8O7 a natural food preservative accounts for the tartmess of citrus fruits. About 730 g of this substance can be dissolved in water making a liter of solution. Howe ver only about 1.5% of it dissociaes. As such it would be considered a     acid. What is the molarity (M) of this solution ? MM (citric Acid)=192 g/mol
