Explain why the freezing point of 0.10 m CaCl2 is lower than the freezing point of 0.10 m CaSO4.
Calculate the volume ( L ) of the solute methanol and the volume ( L ) of the solvent acetone that should be combined to make 7.74 kg of a solution that is 3.12 m methanol.
Two beakers, one containing 0.010M nonelectrolyte sucrose, C12H22O11(aq), the other con-taining pure water, are placed inside a container and sealed. The beakers are left until thewater vapor comes to equilibrium in the container. The levels of the liquid in each beaker atthe beginning of the experi
the value ofcolligative properties of collidal solution are of small order as compared to true solution at same concentration. why?
When 13.66 g of lactic acid, C3H6O3, is mixed with 115 g of stearic acid, the mixture freezes at 62.7 degrees celcius. The freezing point of pure stearic acid is 69.4 degrees celcius. What is the freeezing point constant of stearic acid?
How many quartz of ethylene glycol, C2H6O2 (density = 1.116 g/mL). Will have to be added to 5 gal of water (density = 1 g/mL) to protect an automobile radiator down to a temperature of-10oF? Ethylene glycol is a permanent antifreeze agent.
