Moles of chalk lab answer key

What we have to do, is to calculate the number of chalk molecules needed to write down your name on the board. Here is how we can do that: Take one chalk and weigh it, which will be the first mass (m 1 _1 1 ) Write down your name on the board and after writing it, weigh the chalk again. That will be the second mass (m 2 _2 2 )
