解答:解:(1)单位物质的量的物质所具有的质量,称为摩尔质量(molar mass),用符号M表示.当物质的质量以克为单位时,摩尔质量的单位为g/mol,在数值上等于该物质的相对原子质量或相对分子质量.因此甲醇的摩尔质量为32克/摩尔;根据碳元素质量守恒定律,m+2=8,则m=6,...

The coexistence curves have been successfully described by a combination of the Wegner equation and the expression for the diameter. The power-law dependence of critical amplitudes on molar mass of n -alkane has also been discussed. 展开
The coexistence curves have been successfully described by a combination of the Wegner equation and the expression for the diameter. The molar mass (M)-dependence of critical volume fraction φcmay be expressed as (1−φc)/φc∝M−rand −ris found to be 0.40. 展开 ...
