Calculate the mass of nitrogen dissolved at room temperature in an 83.0 {rm L} home aquarium. Assume a total pressure of 1.0 {rm atm} and a mole fraction for nitrogen of 0.78.
calculate the pH of the 1 L solution of 0.25 M TRIS plus the addition of 0.05 M HCL. Show how many moles of TRIS and TRIS HCL are present after the addition of the HCL. Use the Henderson Hasselbalch equation to calculate the pH?
Provide the newman projections across the C 2 -C 3 bonds for the major conformers after Drawing the zig-zag structures of all the isomers of 2,3-diaminopentane.
How is concentration an intensive property? I mean if you add more amount of a substance(mass), the number of moles increase and so the concentration increases.
