Lab 1:Unknown Density from Mass and Volume Displacement
To know the density from mass and volume
3 unknown metals ( copper, aluminum , iron) . Weight balance . Graduated cylinder . 15 ml water .
1- We put 15 ml of water in
Determination of empirical formula of magnesium oxide
Hypothesis: In this experiment we will determine the empirical formula of magnesium oxide by oxidizing magnesium ribbon with atmospheric oxygen in a crucible. Procedure: First we heat up the crucible t
In this experiment you will observe the dehydration of a hydrated salt, and will calculate both the percent water by mass and the correct formula for the hydrated salt. By making sure the percent error is less than 5%; %Hydration Theoretical-%
