Antoine Lavoisier burned metals in sealed jars. What is your prediction of his experimental results?
The mass of the jar and contents varied unpredictably as the conservation of mass depended upon the metal being burned.
The mass of the jar and contents increased after the metal was burned.
The mass of the jar and contents remained the same after the metal was burned.
The mass of the jar and contents decreased after the metal was burned.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
