Find … WebThe chemical equation for burning gasoline (octane) in air is: 2 C8H18 + 25 O2 -> 16 CO2 + 18 H2O b. To find the molar mass of octane, we need to add up the molar masses of all the atoms in one molecule of octane: molar mass of octane = (8 x molar mass of carbon) + (18 x molar mass of hydrogen) = (8 x 12.01 g/mol) + (18 x 1.008 g/mol)

WebBy measuring the density of the gas at a known temperature and pressure, the molar mass of the gas can be calculated using the ideal gas law, which states that the pressure, volume, and temperature of an ideal gas are related by the equation: PV = nRT, where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of the … WebGases. Density and molar mass are calculated by modifying the ideal gas law equation. What we do is first replace the moles (n) in PV = nRT with mass over the molar mass: …

WebThis equation tells us that gas density is directly proportional to the pressure and molar mass, and inversely proportional to the temperature. For example, CO 2 (molar mass = 44 g/mol) is heavier than N 2 (molar mass = 28 g/mol) or O 2 (molar mass = 32 g/mol), and is therefore denser than air. WebDensity can then be calculated according to a molar form of the ideal gas law : where: , molar mass , ideal gas constant , absolute temperature , absolute pressure Note that the density close to the ground is It can be easily verified that the hydrostatic equation holds: Exponential approximation [ edit]
