| Substance B will diffuse faster through an agar gel than substance A. |
| No answer text provided. |
| The two substances will diffuse at equal rates. |
| Substance A will diffuse faster through an agar gel than substance B. |
Homework Answers
4rth one is correct answer because substance A has small molecular wt. than B and in gel ,small sized particle diffuse fastly due to their low friction with gel.

An alternating copolymer is known to have a number-average molecular weight of 250,000 g/mol and a number-average degree of polymerization of 3406. One of the alternating mers is polystyrene which has a molecular weight of 105_g/mol. Given that the molecular weight of polypropylene is 42 g/mol and that of polyvinyl chloride is 61.5 g/mol, Which of them is the other alternating mer?

A 150 g sample of polyisoprene with a molecular weight of 1000 kg/mol is reacted with 0.75 g of sulfur to produce a rubber network. The product is a 70 cm long strip with a 0.93 g/cm3 density. If you suspend a 10 kg weight from one end of the strip, hung vertically, to what final length will the material stretch? Note that the area to which the force is attached is not given but can be determined by (volume)/(length).
