I NEED A ANSWER FAST PLEASE HELP
NikAS [45]

Answer:

Elevation in boiling point is mathematically expressed as

ΔTb = Kb X m

where Kb =  boiling point elevation constant =  2.53°c/m (for benzene)

m = molality of solution = 3.47 m (given)

∴ ΔTb = 2.53 X 3.47

          = 8.779 oC

But, boiling point of benzene = 80.1 oC

∴ Boiling point of solution = 88.879 oC

Now, Depression in freezing point = ΔTf = Kf X m

where, Kf = freezing point depression constant = 5.12°c/m (for benzene)

∴ ΔTf = 5.12 X 3.47

        = 17.766 oC

But freezing point of benzene = 5.5 oC

∴ Freezing point of solution = -12.266 oC

The area of a square is 361 square feet. What is the distance around the square?
Ray Of Light [21]
The area of a square is its length times its width: l x w = 361
Since the length of a square is the same as its width, replace 'w' with 'l': l x l = 361
l x l = l² = 361 ---> l = √361 ---> l = √361 ---> l = 19 ft.
