An acid solution is 0.100 M in HCl and 0.190 M in H2SO4.What volume of a 0.150 M KOH solution would have to be added to 550.0 mL of the acidic solution to neutralize completely all of the acid?
Somewhere in the Alps, a mountain lake discharges into a 8-m wide stream with boulders across the bottom and gravel along its sides, thus having a Manning coefficient n = 0.041.
Silver consists of two major isotopes with the following percent abundances and atomic masses: 107Ag (51.84% and 106.90509 amu) and 109Ag (48.16% and 108.90476 amu). Calculate the average atomic mass of silver to five significant digits.
