At standard temperature and pressure, or STP, the volume of 4.50 moles of nitrogen gas is 100.8 liters. In chemistry, the volume or space that 1 mole of any gas occupies at STP is given as 22.4 liters, or 22.4 liters/1 mol. By using this information, the calculation to find the volume of 4.5 moles involves multiplying 4.5 mole by 22.4 liters/1 mol.
Know MoreAnother method to find the answer is by using the Ideal Gas Law given as P x V = n x R x T, where at STP, the temperature is 32 degrees Fahrenheit or 273 degrees Kelvin, the constant R is 0.082057 L atm/mol K degrees, n is the number of moles and P is the pressure of 1 atm. By expressing the Ideal Gas Law as V = (n x R x T) and substituting for the variables n = 4.5, T =273 K, R= 0.082057, P= 1 atm, it is possible to find the volume as 100.8 L.

Full Answer >Molecular nitrogen (N2) is not, by itself, a greenhouse gas, as it does not absorb heat in the frequency range of terrestrial radiation. Some nitrogenous compounds, however, such as nitrous oxide (N2O), do act to retain heat and drive greenhouse warming.
Full Answer >The density of carbon dioxide at STP is 1.964 grams per liter (g/L). One mole of an ideal gas at standard temperature and pressure has the volume 22.4 liters. The mass of the ideal gas can be calculated using its molecular weight: density = molar mass/molar volume.
Full Answer >It takes 4.8 moles of sodium hydroxide (NaOH) to neutralize 2.4 moles of sulfuric acid (H_{2}SO_{4}). The process for solving the correct number of moles of NaOH involves the use of the mole ratio between NaOH and H_{2}SO_{4}.
