If You Heated 100 Grams Of Powdered Mercuric Oxide To Produce 93 Grams Of Liquid Mercury How Much Oxygen Would Be Released

Answer 1

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 = ?

Answer 2

I really don't know im not smart

Answer 3
