1. (4 points) Given that the average molecular weight of an amino acid is 110 daltons (Da), determine the following. Remember to convert between daltons and kilodaltons (kDa) where necessary. Each of your answers must be numerically correct and expressed in proper units (1 pt) and show how the value was arrived at using the amino acid molecular weight above (1 pt) for you to receive full credit. A. A molecule of human a-tubulin has a molecular weight of 50.1...
Assume you were given a mixture consisting of one molecule each of all possible sequences of a smallish protein of molecular weight 4800 daltons. If the average molecular weight of an amino acid is, say, 120 daltons, how much would the sample weigh? How big a container would you need to hold it? What does this calculation tell you about the fraction of possible proteins that are currently in use by living organisms (the average molecular weight of proteins is...
Estimate the molecular weight the identical subunits in the picture. Use the value 110 Da as the average molecular weight of an amino acid.
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?

8.a) A random poly(styrene-butadiene) copolymer has a weight-average molecular weight of 467,500 g/mol and a weight-average degree of polymerization of 5500. Calculate the fraction of styrene (C:Hg) and butadiene (C4H6) mers in this copolymer. Atomic weights: C-12, H-1 b) What weight % sulphur must be added to vulcanize polyisoprene (mer weight = 68) by crosslinking one half the possible sites. In this elastomer, each pair of mers has two possible crosslink sites. Assume three sulphur atoms are involved in each...
Fill in the following information for Adipic Acid: molecular weight, g or ml, mole, melting point, boiling point, and density. Example. 3-phenyl-1-propanol MW: 136.19, g or mL: 0.20g, mole: 0.0015, MP: -18, BP: 235, density: 1.008. Can someone please SHOW how to get g/mL for Adipic Acid, someone on Chegg wrote 0.5g , but how is it 0.5g, as well as filling it in?? And can you also explain why 3-phenyl-1-propanol is 0.20g. Thank you
