What is the molal concentration of a sucrose (C12H22011) solution whose freezing point is -2.00 °C? The Kf for water is 1.86 °C/m.

The molal concentration of sucrose solution is 1.07 m

Explanation:

Depression in freezing point is given by:

= Depression in freezing point

i= vant hoff factor = 1 (for non electrolyte such as sucrose)

= freezing point constant =

m= molality

Putting in the values:

Thus molal concentration of sucrose solution is 1.07 m

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
