\(N=\dfrac{240}{20\%}=1200\left(nu\right)\)
\(L=\dfrac{N}{2}\cdot3,4=\dfrac{1200}{2}\cdot3,4=2040\left(A^o\right)\)
\(M=N\cdot300=1200\cdot300=360000\left(đvC\right)\)
Ta có: \(2A+2G=1200\); mà A=T=240(nu)
\(\Rightarrow G=X=360\left(nu\right)\)
Số liên kết hidro: \(H=2A+3G=2\cdot240+3\cdot360=1560\left(lk\right)\)
