suppose a cup of coffee at the campus coffee shop is 1.50 and a cup of hot tea is 1.25 and a students beverage budget
NaOH solution is used to determine the amount of Mg(OH)2 in a sample of milk of magnesia, (molairty of NaOH is 1.172M). A 10.0 gram sample of milk of magnesia is required with 8.00 mL of 6.00 M HCl.
The enthalpy of vaporization of water at 373 K and 1 bar is 40.7 kJ/mol and the molar heat capacities are 75.3 J/(mol K) for liquid and 33.6 J/(mol K) for gaseous water. Find the enthalpy of vaporization of water at 273 K and 1 bar.
Classify the following solutions as saturated, unsaturated, or supersaturated, based on your graph. Note that c. and d. require you to convert from the concentrations give to g/100 g H2O before you refer to the graph.
