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?

An aqueous solution of sucrose (C12H22O11) is prepared by dissolving 7.4045 g in sufficient deionized water to form a 100.00 mL solution. Calculate the molarity of the solution. Do you mind showing work? I would assume that (given) gram weight (times moles present/divided by mole(s) of compound) then divided - again by compound weight will give a percentage, then divded by the .....that's where I'm a little lost. thanks
