1、偶极距测定数据处理T=297.05KP=102.06KPa1、折光率的测定折光率的测定N环己烷0.050.100.150.200.30水第一次1.42471.42251.41971.41821.41441.40691.3322第二次1.424491.42251.41981.41801.41401.40721.3324第三次1.42521.42301.42061.41781.41361.40751.3328平均值1.4247971.4226671.4200331.4181.4141.40721.332467数据处理如下加上x

2、=0.15时候的数据，会使得线性不好，故舍去该组数据；由数据可知：n1=1.4254因此：γ=-0.0592/1.4254=-0.041532、密度的测定密度的测定环己烷0.050.10.150.20.3水空瓶/g10.184310.183910.19810.19710.19710.19710.197空瓶+样品/g18.987718.984719.06219.11019.16419.26921.543样品/g8.80348.80088.8648.9138.9679.07211.346体积/cm310.00010.00010

4、4.85-7.59）/(2.015-1)=2.17(pF)由ε溶=（C/溶-Cd）/C0，可算出：ε(环己烷)=2.022388同理可得ε(0.05)=2.291045ε(0.10)=2.628253ε(0.20)=2.902622ε(0.30)=3.347015得下表：浓度环己烷0.050.10.150.20.3ε2.0223882.2910452.417912.6282532.9026223.347015作图如下：3ε1=2.021α=4.3539/2.021=2.15434、求P2∞、R2∞=3*2.1543*2.0

5、15*84.16/[(2.015+2)2*0.8758]+(2.015-1)*(88.11-0.1193*84.16)/[(2.015+2)*0.8758]=R2∞=(n12-1)/(n12+2)*(Μ2-βΜ1)/ρ1+6n12Μ1γ/[(n12+2)2*ρ1]=[（1.42542-1）/（1.42542+2）]*[(88.11-0.1193*84.16)/0.1193]+[6*1.42542*84.16*(-0.04153)]/[（1.42542+2）2*0.8758]=5、求偶极矩μ0=3
