(a) Calculate moles(Mg) = mass(Mg) ÷ molar mass(Mg) (3) Use the mole ratios to calculate the mass of O 2 consumed and MgO produced as shown below: Moles(Mg) : moles(O 2) : moles(MgO) is 2:1:2 (2) Determine the mole ratio (stoichiometric ratio) from the equation, Mg : O 2 : MgO (1) Write the balanced chemical equation for the chemical reaction: The Question: 12.2 g of magnesium metal (Mg (s)) reacts completely with oxygen gas (O 2(g)) to produce magnesium oxide (MgO (s)).Ĭalculate the mass of oxygen consumed during the reaction and the mass of magnesium oxide produced.
Take the exam now! Worked Example of Using Mole Ratio to Calculate Mass of Reactant or Product (c) Use the mole ratio to calculate moles MgO Moles(MgO) : moles(Mg) is 2:2 which is the same as 1:1 (b) Use the balanced equation to determine the mole ratio MgO:Mg

No ads = no money for us = no free stuff for you! Mole Ratio (stoichiometric ratio) The mole ratio (stoichiometric ratio) can be used to calculate the mass of reactants and products in a chemical reaction.The ratio of moles of each reactant and product in a reaction is known as the mole ratio (or stoichiometric ratio).⚛ The ratio of the moles of each reactant and product. ⚛ The ratio of the number of molecules of each type reacting and produced. A balanced chemical equation can tell us:.You need to become an AUS-e-TUTE Member!

GPAW version 1.3.0 released (Oct 2, 2017).Ĭode-sprints moved to first Tuesday of every month (Feb 17, 2017) So we calculate this as follows: Molecular Weight (2 x 1.01) + (1 x 16) Molecular Weight of Water 2.02 + 16. Molecular Weight (number of hydrogen atoms) (H atomic weight) + (number of oxygen atoms) (O atomic weight). GPAW version 1.5.2 released (May 8, 2019). The molecular weight formula which is also used by molar mass calculator is.
