Chemistry

The molal concentration of sucrose solution is 1.07 m

Explanation:

Depression in freezing point is given by:

$\Delta T_f=i\times K_f\times m$

$\Delta T_f=T_f^0-T_f=0.00-(-2.00)^0C=2.00^0C$ = Depression in freezing point

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

K_f = freezing point constant = 1.86^0C/m

m= molality

Putting in the values:

$2.00^0C=1\times 1.86^0C/m\times m$

m=1.07

Thus molal concentration of sucrose solution is 1.07 m
