Molecular Weight Calculator

If you are a middle school student, you must be worried about chemistry, like me. (Be quiet! Don't let my chemistry teacher hear it!)

如果你是一个中学生，你一定很担心你的化学成绩，像我一样。（小声点，别被我的化学老师听见了！）

You also must be worried about the calculation problems in the chemistry exams. The annoying chemical equation, the annoying molecular weight and the annoying format.

你一定也很担心你的试卷中的计算题。那令人头疼的化学方程式、令人头疼的相对分子质量和令人头疼的死板格式。

So this program is made to calculate the relative molecular weight, for most of the middle school students like me. I hope you will enjoy using the program.

所以为了大部分像我一样的中学生，我制作了这个计算相对分子质量的程序。希望大家使用愉快。

There are two versions you can download —— Windows version and macOS version. After downloading, please extract all files in the zip archive to the same folder.

你可以下载Windows版本或者macOS版本。下载完成后，请将压缩包中所有文件解压到同一个文件夹。

Program Shotcut:

程序运行截图：

Note: the result in student mode is really for students, it ignores most of the decimal parts (except Cl's is also 35.5), like Cu's relative atomic weight is 64 in student mode, but in fact, it is 63.6.

注：其中的“Result in student mode”是为学生准备的结果，它省略了大部分元素相对原子质量的小数部分（除了氯的相对原子质量还是35.5），以符合各大考试卷的标准。比如，铜的相对原子质量在学生模式中是64，但是实际上是63.6。

For programmers

The program contains an API. Before using the API, please copy the program and paste it in path directories (like C:\Windows\System32 in Windows and /usr/local/bin in macOS) or in the same directory as your executable file.

程序包含一个API，在使用API之前，请先将本程序拷贝到一个path文件夹中（如Windows中的C:\Windows\System32和macOS中的/usr/local/bin），或者拷贝到和你的可执行文件相同的文件夹中。

The API includes commands below:

API包含如下命令：

molecular-weight-calculator -a [Name]

Calculate the relative molecular weight of [Name].

计算[Name]的相对分子质量并输出。

molecular-weight-calculator -at [Name]

Calculate the relative molecular weight of [Name], and multiply it by 10 (to prevent using decimal parts).

计算[Name]的相对分子质量，乘10并输出（以防止出现小数部分）。

molecular-weight-calculator -s [Name]

Calculate the relative molecular weight of [Name] in student mode.

在学生模式下计算[Name]的相对分子质量并输出。

molecular-weight-calculator -st [Name]

Calculate the relative molecular weight of [Name] in student mode, and multiply it by 10 (to prevent using decimal parts).

在学生模式下计算[Name]的相对分子质量，乘10并输出（以防止出现小数部分）。

Used libs
