The great French chemist Antoine Lavoisier discovered the Law of Conservation of Mass in part by doing a famous experiment in 1775. In this experiment
Lavoisier found that mercury(II) oxide, when heated, decomposed into liquid mercury and an invisible and previously unknown substance: oxygen gas.
1. Write a balanced chemical equation, including physical state symbols, for the
ローロ
decomposition of solid mercury(II) oxide (HgO) into liquid mercury and gaseous
dioxygen.
2. Suppose 54.0 mL of dioxygen gas are produced by this reaction, at a temperature
of 50.0 °C and pressure of exactly 1 atm. Calculate the mass of mercury(II) oxide
that must have reacted. Round your answer to 3 significant digits.
