2、1=1.4254因此：=-0.0592/1.4254=-0.041532、密度的測(cè)定密度的測(cè)定環(huán)己烷0.050.10.150.20.3水空瓶/g10.184310.183910.19810.19710.19710.19710.197空瓶+樣品/g18.987718.984719.06219.11019.16419.26921.543樣品/g8.80348.80088.8648.9138.9679.07211.346體積/cm310.00010.00010.00010.00010.00010.00010.000密度0.880340.880080.88640.89130.89670.90721.1

3、346數(shù)據(jù)處理如下因一二組數(shù)據(jù)出現(xiàn)明顯誤差，故舍棄了前兩組數(shù)據(jù)做圖由上圖可知：1=0.8758 =0.1045/0.8758=0.11933、介電常數(shù)的測(cè)定介電常數(shù)的測(cè)定環(huán)己烷0.050.10.150.20.3c04.854.854.854.864.844.85c溶7.598.318.659.249.9211.14環(huán)己烷:cd=（標(biāo)c/空- c/標(biāo)）/（標(biāo)-1)=（2.015*4.85-7.59）/(2.015-1)=2.17 (pf)由溶=（c/溶- cd）/ c0 ，可算出：(環(huán)己烷)= 2.022388同理可得(0.05)=2.291045 (0.10)=2.628253 (0.20)=

4、2.902622 (0.30)=3.347015得下表：濃度環(huán)己烷0.050.10.150.20.32.0223882.2910452.417912.6282532.9026223.347015作圖如下：1=2.021=4.3539/2.021=2.15434、求p2、r2 =3*2.1543*2.015*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) * (2-1)/1 + 6n121/(n12+2)2*1=（1.42542-1）/（1.42542+2）* (88.11-0.1193*84.16)/
