2HgO ==> 2Hg + O2
mols HgO = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols HgO to mols O2.
Now convert mols O2 to whatever unit you want. The post doesn't say. If grams, then grams O2 = mols O2 x molar mass O2.
If volume at STP, then L = mols x 22.4 L/mol = ?
mols HgO = grams/molar mass = ?
