30.08.2019 The Synthesis and Determination of Empirical Formulation for Magnesium Oxide

Target:

To determine the scientific formula pertaining to magnesium oxide.

Data Collection:

Table one particular Mass of empty crucible, crucible & Mg (roughly 1cm bits of a 15-cm piece of magnesium (mg) ribbon), and crucible +MgxOy. (mass scored with an analytical balance). The mass of crucible + MgxOy was acquired after a continuous process of heating system, letting cool, heating with water enough to immerse the content and letting amazing of the Mg.

16. 04716. 21416. 294

Uncertainty of analytical balance = + 0. 002

*Note that because we could uncertain if Mg offers completely reacted with T-MOBILE in the 1st heating, in the event all the Magnesium have reacted with T-MOBILE instead of In and if water added has completely vaporized in the second heating(with water), the data and the following measurements may not be because accurate.
