    Hi!

    I'm looking for a list of common compounds with corresponding molar mass.

    Does someone knows a link (not a database, where I have to click one by one) of such a list?

    Regards

    Stefanie

    It's been a while since my early chemistry days in high school, and might be totally off... but, can't you find the molar mass of an element on a periodic table? Just take any chemical formula and do the math?

    I agree with Shaderwolf that you can simply calculate the mass of any compound of interest yourself. Or simply look up each one by clicking a database. What is your goal, anyway?

    Ah sorry I forgot to say what I want to do:

    I'm programming a tool-set for the lab and one of the tools is a solution calculator (enter a compound, volume and molarity and get mass). Since I want to have it in two languages (german works allready :-D ) I'm looking for a whole list because it's easer than to translate one by one .

    rephrase your question in the computer science section, instead of using a database, write a program that will calculate the molar mass

    Agreed again. Your program will contain the atomic mass of each element in a simple database. When someone enters the formula of a compound of interest, the program will self-calculate its molar mass!

    That's much more efficient than teaching the program the mass of 10,000 different common substances.

    Yea, I also thought about this improvement. Since it's not my main tool, I will change it later. At the moment it was easier to implement in that way (I'm still beginner ). But you're right, this solution is much nicer...

    Are you using a specific program to create this program? C++ for instance. If you need any help actualy designing the program itself, I believe our computer science friends could lead you through a step by step process. If someone can help you, the program that calculates will not just be more reliable, it will also be easyer to make. If you want a list of common substances, you will have to specify. There are so many, we will need to know the context.

    Thanks, at the moment I was only looking for a fast translation. Later and in another post, I will present the program and ask for some testing. Than we can talk about it in details (after you have seen it).

    I'm programming in Python. Beta release will be soon.
