2HgO ==> 2Hg + O2
mols HgO = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols HgO to mols O2.
Then L O2 = mols O2 x 22.4 L/mol = ?
determine the volume of oxygen calculated at STP which is liberated when 43,4g mercury oxide decomposes completely into mercury and oxygen
