Hi guys! So basically on my lab report, we were trying to find the empirical formula of MgO. We put Mg into a crucible and measured its mass. My teacher told us to measure it with and without the lid in case the lid broke from the heat. One of my calculations of the Mg = 0.246g and the other one the Mg = 0.241g. My calculations are correct, it seems that there was a mistake with the scale.
What do I do? Do I find the average of these values or do I simply just write about this random error in my conclusion? What do I do?
