Patients undergoing an upper gastrointestinal tract laboratory test are typically given an X-ray contrast agent that aids with the radiologic imaging of the anatomy. One such contrast agent is sodium diatrizoate, a nonvolatile water-soluble compound. A 0.378-m solution is prepared by dissolving 38.4 g sodium diatrizoate (NaDTZ) in.l.60 102 mL water at 3 1.2C (the density of water at 31.2C is 0.995 g/cm3). What is the molar mass of sodium diatrizoate? What is the vapor pressure of this solution if the vapor pressure of pure water at 31.2C is 34.1 torr?
Table sugar (C12H22O11) or urea [(NH2)2CO] can be used by road crews to melt ice on roads, but solutions of CaCl2 are generally used instead. Assuming equal costs per pound of substance, why is CaCl2 used instead of table sugar or urea?
6-16 Answer true or false. (a) Solubility is a physical property like melting point and boiling point. (b) All solutions are transparent—that is, you can see through them. (c) Most solutions can be separated into their components by physical methods such as distillation and chromatography.
A martini, weighing about 5.0 oz (142 g), contains 30.0% by mass of alcohol. About 15% of the alcohol in the martini passes directly into the bloodstream (7.0 L for an adult). Estimate the concentration of alcohol in the blood (g/cm3) of a person who drinks two martinis before dinner. (A concentration of 0.00080 g/cm3 or more is frequently considered indicative of intoxication in a normal adult.)
7.0 mL of 3.0 M NaOH are diluted with water to a volume of 400 mL. (a) Determine the molarity of the resulting solution. How many moles of NaOH there are in 7.0 mL of 3.0 M NaOH? Hint: Use Eq. 1 and make sure the volume is in liters: MA = mol A / soln (L) OR mol A = MA x V ___________ moles (b) The total number of moles of NaOH is not changed on dilution. The molarity after dilution can therefore be found by MA = mol A / soln (L) OR mol A = MA x V using the final volume of the solution. Calculate that molarity.
