Presentation on theme: "Lab Review for Final Exam. Experiment #1: Density Density = Mass/Volume Volume = length x width x height Units = g/mL or g/cc or g/cm 3 Density Column."— Presentation transcript:
Relative Uncertainty is the ratio of the absolute uncertainty of a measurement to the best estimate. It expresses the relative size of the uncertainty of a measurement (its precision). For example, The measurement 25.4 + 0.1 cm
Experiment #4: Composition of a Heterogeneous Mixture Filtration Distillation Decanting Chromatography Electrolysis % Composition
Experiments #7 & #8: Quantitative Analysis of Hydrates Hydrate Calculate unknown value of a hydrate Calculate mass of water produced in a hydrate Calculate number of moles of water in a hydrate Methane hydrate When organic material decomposes it releases methane, also known as swamp gas. Combine water and swamp gas under low temperatures and high pressures and the result can be a frozen lattice-like substance called methane hydrate. This crystalline combination of a natural gas and water looks remarkably like ice but burns if lit with a flame.
If 16.4 grams of oxygen gas react with excess hydrogen, what mass of water is produced?
