Calculations (Relative atomic masses: Mg=24, C=12, O=16)2. (a.) calculate the mass of magnesium oxide formed when 12 g ofmagnesium is heated in oxygen. |
|
Answer» gnesium (Mg) and Oxygen (O) combine in the ratio = 3:2 to FORM compound MAGNESIUM oxide (MgO). It follows Law of Constant proportions. • 3G of Mg COMBINES with = 2g of O. • 12g of Mg combines with = 2 × 12/3 = 8g of O. |
