A sample of water is found to contain 0.059 ppm of Pb2+ ions. Calculate the mass of lead ions per liter of this solution (assume the density of the water solution is 1.0 g/mL) 1.2E-2 g/L Pb2+ 5.9E-8 g/L Pb2+ 5.9E-5 g/L Pb2+ 1.2E-5 g/L Pb2+ 2.9E-10 g/L Pb2...

What is the equilibrium concentration of carbon dioxide in water that is in contact with air at 25 °C and 2.55 atm. The mole fraction of CO2 in air is 3.01 x 10-4. The Henry's law constant for carbon dioxide is 4.48 x 10-5 M/mmHg. 0.583 M 8.68E-2 M 6.72 M...

Consider the below three solvents and the corresponding values of Kf for each. Prove, using the formula for Kf, which one of these solvents would allow for the most sensitive procedure for determining the molar mass by the freezing point depression method...
