What is the volume of 1 mole of hydrogen gas? One mole of any gas occupies the same volume when measured under the same conditions of temperature and pressure. In this experiment you will calculate the volume of 1 mole of hydrogen at room temperature and pressure. Intended lesson outcomes By the end of this practical you should be able to: • further develop skills in manipulating apparatus and accurate measurement; • use the mole concept; • calculate the molar volume at room temperature

Analysis of a Chemical Mixture Using the Ideal Gas Law The objective of this experiment was to determine the composition of the NaNO2 mixture in the net ionic reaction of NO2-(aq) + HSO3NH2(aq) → HSO4-(aq) + H2O(l) + N2(g) in unknown mixture number nine. It was known that NO2-(aq) and HSO3NH2(aq) were in a stoichiometric 1:1 molar ratio. In trial one the percent mass of NaNO2 in the unknown mixture was 59.30%. In trial two‚ the percent mass of NaNO2 was 63.47%. Lastly in trial three

This information can then be used to calculate original oil in place (OOIP) and original gas in place (OGIP). Hence‚ for a given exploration prospect‚ explorers and commercial analysts can use this crucial information to determine whether a prospect is financially viable. This paper seeks to discuss bulk rock volume and its importance in determining the amount of hydrocarbon in a reservoir. An instrument

Alexis Becker Pre-Lab Experiment 7 Avinash Pallagani Investigating Stoichiometry with sodium salts of carbonic acid 4/2/14 A summary of the concepts: The purpose of this lab is to better understand “stoichiometry”. We will be reacting sodium carbonate (NaHCO)3 and sodium carbonate (Na2CO3) with hydrochloric acid to produce sodium chloride‚ water‚ and carbon dioxide. The balanced chemical reaction looks like this: NaHCO3 + HCl = NaCl + H2O + CO2 CAUTION: Be especially

SOLIDS: Mass‚ Volume and Density Measurements A. Overview Review Sections 1.4 - 1.6 in your textbook (Chemistry: The Central Science‚ 9th Ed. ‚ Brown‚ LeMay‚ Bursten‚ & Burdge) This experiment will introduce you to a very important concept in science‚ especially chemistry: DENSITY. Density is the relationship between the mass of an object and the volume which it occupies. Solid substances generally have the greatest density‚ normally in the range of 1 - 25 g/cm3. Most liquids have densities between

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Hess’s Law and the Molar Enthalpy of Combustion for Magnesium Purpose: The purpose of the lab ultimately is to find the molar enthalpy of magnesium. This is done by finding the enthalpy changes of reactions (2) and (3). The enthalpy changes of reactions (2) and (3) along with the enthalpy change given for reaction (4) can be used to arrive at a value of the molar enthalpy of combustion of magnesium by using Hess’s Law. Hypothesis: By using Hess’s law to calculate the molar enthalpy of combustion
