<p>The question/ experiment that I was given was to place one drop of 1% of three solutions into the holes that were in a plate of agar. After 60 minutes we were told to measure how far the solutions had diffused. However, my answer was mistaken. And the question is what variables or mistakes could I have made. What could have gone wrong? Also isn't it the lighter the MW of the solution the faster it diffuses?</p>
<p>Please anyone</p>
<p>well the thing is the lighter the item that you are dissolving, the faster it takes, however since that was held constant, that cant be a source of error. id say that one answer could be human. such as put i little more in one than another or something like that. or it could also have something to do with the composition of the solution. do you know which each solution was?</p>
<p>CMU, I'm curious...what program/class are you in that you are doing all of this work over the summer? Is it the PA Governor's School of the Sciences held at CMU? I've heard that it is AWESOME.</p>
