A solution of salt (molar mass 90 g mol -1) in water has a density of 1.29 g/mL. The concentration of the salt is 35% by mass. a. Calculate the molality of the solution. b. Calculate the molarity of the solution. c. Calculate the total number of moles in the solution. d. Calculate the mole fraction of the salt in the solution
Using the equation E0cell = E0cathode - E0anode, and the reference value of E0 for Cu(II)/Cu(s) for the role that copper plays in this overall cell reaction, determine the value of the standard potential for the half-reaction Zn2+(aq) + 2e- -> Zn(..
Suppose a mercury thermometer contains 3.450 of mercury and has a capillary that is 0.180 in diameter. How far does the mercury rise in the capillary when the temperature changes from 0.0C to 25.0 C? The density of mercury at these temperatures is..
