gram molecular mass

Relative molecular mass is the ratio of the mass of one molecule of a substance to the mass t h of a carbon atom, or 1 am..

Silver salt method is used for determining the molecular masses of carboxylic acids. This method is based on the fact that they form insoluble silver salts, which upon heating decompose to leave a residue of metallic silve..

The relation between colligative property and molecular mass of the solute is based on the following assumptions: i) The solution is dilute so that Raoult's law is obeyed. ii) The solute neither undergoes dissociation nor association in solution. When the molecular ..

The relation between colligative property and molecular mass of the solute is based on the following assumptions: i) The solution is dilute so that Raoult's law is obeyed. ii) The solute neither undergoes dissociation nor association in solutio..

In order to determine the molecular mass of unknown non volatile compound, a known mass (say w g) of the compound is dissolved to prepare a known volume (say v liters) of solution. The osmotic pressure of the solution is determined and the molar mass is calcu..

The quantity of an element whose mass in grams is numerically equal to its atomic mass. In simple terms, atomic mass of an element expressed in grams is the gram atomic mass or gram atom. For example, the atomic m..

D T b = k b m (1) If W B gms of the solute is dissolved in W A gms of the solvent then (where M B is the molar mass of the solute) From (1) and (2)..

Question 21 - Question: What is the mass of 0.2 mole of lead nitrate? (N=14, O=16, Pb=207). Answer: Gram molecular weight of Pb(NO 3 ) 2 = 207 + (2 x 14) + 2(16 x 3) = 207 + 28 + 96 = 331 1 mole of Pb(NO 3 ) 2 is 331 g Therefore 0.2 mole of Pb(NO 3 ) 2 is 331 x 0.2 = 6..

The empirical formula of the compound is written. The empirical formula mass is calculated by adding the atomic masses of all atoms present in the empirical formula. The molecular mass or molar mass is obtained from experiment or from the va..
