Homework Statement
i'm finding out the empirical formula of magnesium oxide for chem class.
this is my data
trial 1 trial 2
1. mass of crucible, lid, and metal (g) 25.2 21.25
2. mass of crucible, lid, and product (g) 25.4 21.23
3. Mass of crucible and lid (g) 25.0 21.12
Questions:
1. calculate the mass of the magnesium metal and the mas of the product
2. determine the mass of the oxygen consumed.
3. calculate the number of moles of magnesium and the number of moles of oxygen in the prodcut.
4. determine the empirical formula for magnesium oxide
