How many moles of analyte are present in 10 micromolar solution that occupies 1% of the length of 60 micrometer × 25 micrometer capillary?

A container is divided into two compartmentsby a membrane that is fully permeable to water and small ions.Water is added to one side of the membrane (side A), and a 5%solution of sodium chloride (NaCl) is added to the other (side B). Inwhich direction will water molecules move? In which direction willsodium and chloride ions move? When the concentration is equalon both sides, will diffusion stop?

At what temperature (in °C) will a solution in which 66.28 grams of iron (III) chloride has been added to 1,291 grams of water boil?  The boiling point of water is 100.00°C.  You should use the experimental value of the van't Hoff factor for this calculation.   (5 significant figures)

Rubbing alcohol is an aqueous solution containing 85% isopropyl alcohol by volume. How would you prepare 125mL rubbing alcohol for pure isopropyl alcohol?
