Asolution was prepared by mixing 50 μl of 8 mg/ml octadecane internal standard with 100 μl of 12 mg/ml of a dodecane standard with 350 μlhexane. the octadecane peak area was 357 while the dodecane area was 516. calculate the response factor. the same internal standard was used to prepare an unknown sample of dodecane. the sample was prepared by mixing 50 μl of 8 mg/ml octadecane and 100 μl dodecaneof unknown concentration. the areas were 382 for octadecane and 463 for dodecane. calculate the unknownconcentration. remember to use significant figures.

Evaluate this exponential expression,8. (2 + 3)2 – 42

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
