Which has a greater boiling point urea or glucose and why?
melting point of urea is 135 Celcious
How do you prepare 6 molar urea?
Mol. Wt 60.0 So 60.0 gm in 1L is 1M 60*6= 360gm in 1L is 6M urea
What is the freezing point of 'urine'?
freezing point - 135 degree celsius boiling point - 150 degree celsius It depends on the concentration of your solution. The freezing point of 2.0 g of Urea in a 10 mL solution of pure water begins to freeze at -6.7 degrees celsius.
Is aqueous solution of urea a conductor?
Yes, but a poor one
What is the concentration of solution which contains 16g of urea in 120g of solution?
16 / 120 * 100% = 13.3% (w/w)
Which has higher boiling point Urea or Sodium chloride?
urea
Which has a greater boiling point urea or glucose and why?
melting point of urea is 135 Celcious
How you would make a 0.5 molar solution of urea with a final solution volume of 0.5 liter.?
Dissolve 15,015 g urea in 0,5 L demineralzed water; work with a thermostat at 20 oC and a volumetric flak.
A 5 percent urea solution is hypotonic to a 10 percent urea solution?
true
How do you make 1L OF 1M OF UREA?
The chemical formula of the urea is CH4N2O. The atomic mass of Carbon is 12. That of hydrogen is 1*4. That of nitrogen is 14 * 2. That of oxygen is 16. So total atomic mass of urea comes to be 60. So you have to add 60 grams of urea to one liter of the water to make one molar solution.
A chemist dissolved 15.0g of urea, NH2CONH2, in 200mL of water in a styrofoam calorimeter. A temperature change from 25.0°C to 17.2°C is measured. Calculate the MOLAR ENTHALPY of solution for the UREA?

Is urea a base in water but acid in liquid ammonia?
The hydrolysed solution of urea is basic.In liquid ammonia urea act as proton donor and the solution is acidic.
What is urea N 40?
Usually it means a 40% solution of Urea.
Can urea neutralise pH water?
Urea water solution is neutral.
Is aqueous solution of urea an electrolyte?
This solution is not an electrolyte.
What is the mass of one mole of urea (CN2H4O)?
Urea is an organic compound. Its chemical formula is CO parenthesis NH2 and 2 on the outside. The molar mass is 60.06 grams per mol.
How do you prepare 6 molar urea?
Mol. Wt 60.0 So 60.0 gm in 1L is 1M 60*6= 360gm in 1L is 6M urea
