Answer to Question #4321 in Inorganic Chemistry for Samay Patel

Question

A gas 'x' is collected over water at 17 degree celcius and 750 mm pressure.If the volume of the gas collected is 50 cc then calculate the volume of the dry gas at standard temperature pressure and at 17 degree celcius the vapour of pressure is 14 mm

Answer 1

Averagemolecular weight of amino acid (AA) is 105 DaAveragemolecular weight of nucleotide(Nucl.) is 345 Da
Averagelength of nucleotide is 0,34 nm
N(AA) = 40000/105 = 381
N(Nucl.) = 381*3 = 1143
l(Nucl.) = 1143*0.34 = 388.62nm
m(Nucl.)_1strand = 1143*345 = 394335Da = 394.3 kDa
m(Nucl.)_2strand = 1143*345*2 = 788670Da = 788,7 kDa
