Reacting mass calculations tes

WebThe balanced equation shows that 5 moles of oxygen are needed to completely react with 1 mole of propane Therefore the volume of oxygen needed would be = 5 moles x 150 cm 3 = 750 cm3 The total number of moles of gaseous products is = 3 + 4 = 7 moles The total volume of gaseous products would be = 7 moles x 150 cm 3 = 1050 cm3 Exam Tip WebWhat mass of Mg will be produced when 86.4 g of K are reacted? MgCl 2 (s) + 2K (s) → Mg (s) + 2KCl (s) Solution We will simply follow the steps: mass K → mol K → mol Mg → mass Mg In addition to the balanced chemical equation, we need the molar masses of K (39.09 g/mol) and Mg (24.31 g/mol).

Webmass 1 = crucible + lid mass 2 = crucible + lid + magnesium mass 3 = crucible + lid + product This should allow them to calculate the mass of the mass of the magnesium (mass 2 – mass 1) and the mass of the product (mass 3 – mass 1). They could also calculate the increase in mass (mass 3 – mass 2), which corresponds to the mass of oxygen.
