If a non-volatile salt produces four ions after dissociation then what will be the change in its molecular mass and colligative property of its solution?

If an object weighs 6 N on earth what will be its weight on moon ? What will be the change in its mass ?

The vapour density of ethane is 8. What is its molecular mass and gram molecular mass ?

Why is the molecular mass determined by measuring colligative property in case of some solutes is abnormal ?

Properties such as boiling point, freezing point and vapour, pressure of a pure solvent change Propeties such as boiling point, freezing point and vapour, pressure of a pure solvent change when solute molecules are added to get homogeneous solution. These are called colligative properties. Applications of colligative properties are very useful in day-to-day life. One of its examples is the use of ethylene glycol and water mixture as anti-freezing liquid in the radiator of automobiles. A solution M is prepared by mixing athanol and water. The mole fraction of ethanol in the mixture is 0.9 Given Freezing point depression constant of water (K_(f)^("water"))=1.86 K kg "mol"^(-1) Freezing point depression constant of ethanol (K_(f)^("ethanol"))=2.0 K kg "mol"^(-1) Boiling point elevation constant of water (K_(b)^("water"))=0.52 kg "mol"^(-1) Boiling point elevation constant of ethanol (K_(b)^("ethanol"))=1.2 kg "mol"^(-1) Standard freezing point of water =273 K Standard freezing point of ethanol = 155.7 K Standard boiling point of water =373 K tandard boiling point of ethanol =351.5 K Vapour pressure of pure water =32.8 mmHg Vapour presure of pure ethanol =40g Hg Molecular weight of water =18 g"mol"^(-1) Molecules weight of ethanol =46 g "mol"^(-1) In answering the following questions, consider the solutions to be ideal dilute solutions and solutes to be non-volatile and non-dissociative. when solute molecules are added to get homogeneous solution.

Explain the term 'colligative property'. Why do we sometimes get abnormal molecular masses of the substances using colligative properties of the solution?

A solution contains non-volatile solute of molecular mass M_(2) which of the following can be used to calculate the molecular mass of solute in terms of osmotic pressure? ( m_(2) =mass of solute,V=volume of solution, pi =osmotic pressure)

A certain gas takes four times as long as to out as to effuse helium. Its molecular mass will be
