Only if the calculated molar mass is higher than the actual molar mass of the solute, the calculated molar mass is considered to be abnormal molar mass.

Correct Answer: False
When we correlate molar mass with osmotic pressure as a colligative property, we sometimes encounter a situation where the calculated molar mass of the solute is either higher or lower than the actual molar mass. This is called the abnormal molar mass. Abnormal molar mass occurs as a result of dissociation or association of molecules.

How is the molar concentration of solute in stationary phase related to molar concentration of solute in the mobile phase?

L is older than M and taller than N. O is younger than P, older than N and shorter than Q. R is older than S, younger than N, shorter than S and taller than Q. S is older than L, M, O, P, Q, R and S is necessarily false?

Estimate the interfacial solute concentration in the two liquids when the solute concentration is 45000 kg-moles/m3, interfacial solute concentration in liquid is 40000 kg-moles/m3, diffusivity is 2.5 × 10-11 m2/s and the length of the tube is 5m3 and the partition coefficient is 0.25.

The following question is based on the given data for an examination. A. Candidates appeared 10500 B. Passed in all the five subjects 5685 C. Passed in three subjects only 1498 D. Passed in two subjects only 1250 E. Passed in one subject only 835 F. Failed in English only 78 G. Failed in Maths only 275 H. Failed in Physics only 149 I. Failed in Chemistry only 147 J. Failed in Biology only 221 How many candidates passed in at least four subjects ?

Pavan and Sravan are two persons. If Pavan works with his actual efficiency and Sravan twice of his actual efficiency then it takes 25 days to complete the work. But If Pavan works twice of his actual efficiency and Sravan with his normal efficiency then the work is completed in 20 days. How many days would it take if Sravan alone works with his actual efficiency (in Days)?

When actual loss is . . . . . . . . than the estimated loss, the difference between the two is considered to be abnormal loss.

When actual loss is . . . . . . . . than the estimated loss, the difference between the two is considered to be abnormal gain.

Consider the following statements about emulsion SBR and solution SBR. I. Solution SBR has higher content of non-rubber materials than emulsion SBR II. Solution SBR has higher molecular weight but broader molecular weight distribution than emulsion SBR III. Solution SBR has higher cis-1,4-polybutadiene content than emulsion SBR Which of the following statements are true?

In reverse osmosis, the water travels from lower solute concentration to higher solute concentration.

The normal cost of normal output is Rs. 3,000; value of abnormal loss is Rs. 450 and normal output is 200 units. The units of abnormal loss would be-
