Molarity Lab day 2

On the second day of the lab, there wasn't much of the procedure to be done. The solid from the solution had sat overnight and dried in the filter paper that we used. All we had to do was use the same balance as we did in day one to weigh the mass of the product made. With the two masses, we were able to subtract to then find the difference. Then, we worked backward in a molarity problem to find the molarity of the silver nitrate that was at the crime scene. We converted the mass that we had found to grams, used the mol to mol ratio, and divided by 0.01L, which was the amount of the unknown solution that we used. In the end, we came to the conclusion that Mr. Green was our suspect because the molarity we calculated fit within the range of his description. Finally, we had to make a lab report with our partner over the entire lab.
Here are some links to help with the calculations that we did in our lab:
