Answer:
Isotonic solutions are those which have same osmotic pressure.

Π = (n/v)RT

Π = Osmotic pressure

C = (c/v) = concentration

n = number of moles

R = Gas constant

T = Temperature

So,  Π(urea) =  Π(glucose)

[n(urea) / v] RT = [n(glucose) / v]RT

Mass(urea) / molecular mass(urea) = Mass(glucose) / molecular mass(glucose)

1/60 = 1/180

n(urea) = 0.0166 moles in 1 L

n(glucose) = 0.0055 moles in 1 L

So the staement is false.
