At standard Temperature and Pressure (STP) the molar volume (Vm) is the volume occupied by one mole of a chemical element or a chemical compound. Learn more about molar volume formula and related problem.
molar volume,the volume occupied by amoleof a substance atSTP. According to Avogadro's law, at a given temperature and pressure a given volume of any gas contains the same number of molecules. At STP 1 mole of gas occupies 22.414 liters. This volume is what is usually meant by the mola...
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 the molar mass of the gas can also be calculated from the same equation. Like any other calculations with the molar mass...
2. Calculate the molar amount of hydrogen gas that was produced in your reactions. 3. Calculate the volume of 1 mole hydrogen gas (molar volume) at STP. 4. Compare your molar volume, at STP, with the accepted value of an ideal gas at STP, 22.4 L/mol. If the values do not compare...
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 ...
The Determining the Molar Volume of a Gas Classic Lab Kit for AP® Chemistry involves determining the volume of one mole of hydrogen gas at standard temperature and pressure (STP). A water displacement technique yields hydrogen for analysis. See more product details Product Details ...
The molar volume of an ideal gas is the volume of the gas under a given condition of temperature and pressure. The molar volume of an ideal gas at STP (0∘C and 1 atm) is 22.4 L/mol. It means that an equal number...
(Hint: use stoichiometry. Convert from g of Mg to moles of Mg to mol H2) # moles H2 = Find the pressure exerted by the H2 gas in the tube: PH2 = Pbarometric - PH2O Convert room temperature from °C to Kelvin: K = °C + 273 Find the volume of the H2 gas at STP: P1V1 ...

Molar mass = (" Weight of the substance x Molar volume")/("Volume of the substance at STP") Molar volume at STP = 2.24 xx 10^(2)m^(3) = 22.4 L (or) 22400 cc. Molar mass of the gas at STP = (23.2xx22.4)/20 = 25.984 g .
