There's an App for that!
For my students who have smart phones I would recommend that you download a free app called CMM - molar mass calculator to your phone. IF you do this, then I will periodically allow you to use your cell phone for work in class. Cell phones cannot however be used during tests/exams, so even though you are allowed to use the app for help, you will still need to understand how to do the work yourself
