I start with 46.8 g HgO. What is my theoretical yield of O2? B. I actually collect 2.30 g of O2. What is my percent yield of O2?

Question

2HgO=2Hg+O2

partial answer: 3.XX g O2 and 6X.XX%

Answer 1

This is similar to the NaBr problem I just answered. One extra step will be required--considering the coefficients, the theoretical yield of O₂ needs to be calculated with multiplication by the factor of 1 mol O₂ / 2 mol HgO.
