The volume of hydrogen collected by water displacement is measured and corrected for differences in temperature and pressure in order to calculate the molar volume of hydrogen at STP. Complete for 24 students working in pairs. Determining the Molar Volume of a Gas Inquiry Guidance & AP...
Purpose:To determine experimentally the volume of 1 mole of hydrogen gas at STP. Materials and Equipment: gas-measuring tubelarge deep container for equalizing gas pressure in tube one-hole stopper10-mL graduated cylinder ring standmetric ruler ...
What is the molar mass of gas that, at STP, has a volume of 100ml and a mass of 0.125g? Molar Mass of a Gas: We are familiar with the pressure (P), volume (V), temperature (T), and number of moles (n) of gas in the Ideal Gas Law equation but ...
Molar Volume:Molar volume is described as the volume of 1 mole of any substance at a specific pressure and temperature. In other words, the volume occupied by Avogadro's number of molecules or 1 mole is known as molar volume and keeping all other variables pressure,...

Vapour density of a compound is defined as the ratio of mass of a certain volume of gas to the mass of the same volume of hydrogen gas under conditions of temperature and pressure. Vapour density=Mass of certain of gas(22.4L)at STPMass of same volume ofH2gas(22.4L)at STP =Mw2 ...
STP the temperature must be at 0°C or 273 Kelvin and I atmosphere of pressure. A volume of the gas contains a small number of molecules when comparing it to both liquids and solids. Gases are also called compressible fluids, unlike liquids. Gasses can be compressed while liquids are ...
mol Mg, hence 0.0033 mol H2. Once again, using the same state of gas law, we can determine the volume of hydrogen at STP (V2 = 0.090L (738 torr / 760 torr) * (273K / 296K)) to be 0.081L. Dividing 0.081L by 0.0033mol, we find the molar volume of hydrogen to be 24.5L/mol...
Ed.). If the volume (V), temperature (T) and total pressure (P gas ) of the collected gas are measured, the ideal gas law can be used to determine the moles of hydrogen produced by the sample: RT n V P gas gas = (Equation 1) ...
We are given the following data: The mass of the gas at standard temperature and pressure (STP), m = 21.1 g The volume of the gas at STP, V = 14.1...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask...
