CalCulate of MolarMass.py用于计算化合物的分子量。这是笔者在学习分析化学的时候为了减轻查阅资料的负担而写出来的， 因为Mathematica的数据库经常需要联网更新而没有它设计的那样好用。
CalCulate of MolarMass.py can be used to calculate the molarmass of compound.i write it to lower the burden in look up for data in database,for Mathematica's one often need to up-to-date and unable to work as expected.
后者的使用请直接输化学式，下角标请直接输数字（1位数），离子符号等请忽略，括号暂时不支持。
to use the last one,input the chemical formula straintly.input just numbers（） for subscript and don't try to input "+"or"-"or sth else.the support to "()" is inexist now.
