One pound-mole (lbmol) is equivalent to approximately 453.6 gram-moles (gmol).
gmol-1 refers to grams per mole and is a unit of measurement commonly used in chemistry to express molar mass or molecular weight. It represents the mass of one mole of a substance in grams.
Assume the car gets 30 miles per gallon of octane burned.Voct = 15000 mi / 30 mi/gal = 500 galmoct = Voct / doct = ( 500 gal ) / ( 6.0 lbm / gal ) = 83.33 lbm octanenoct = moct / Moct = ( 83.33 lbm ) / ( 114.29 lbm/lbmol ) = 0.7291 lbmolnCO2 = ( 0.7291 lbmol C8H18 ) ( 8 mol CO2 / mol C8H18 ) = 5.833 lbmol CO2nCO2 = ( 5.833 lbmol CO2 ) ( 453.6 gmol CO2 / lbmol CO2 ) = 2646 gmol CO2VCO2 = ( nCO2 ) ( R ) ( T ) / ( P )VCO2 = ( 2646 mol ) ( 0.08206 atm - L / gmol - K ) ( 298.2 K ) / ( 1.01 atm )VCO2 = 64100 L at 25 C and 102 kPa
The rate of diffusion of a gas is inversely proportional to the square root of its molar mass. Since argon is heavier than neon (molar mass of 40 g/mol compared to 20 g/mol), argon will diffuse more slowly than neon.
The rate of effusion of a gas is inversely proportional to the square root of its molar mass. Helium has a molar mass of 4.0 g/mol, while sulfur dioxide has a molar mass of 64 g/mol. Therefore, the rate of effusion of SO2 will be √(4.0/64) = 1/4 times that of helium. In other words, sulfur dioxide will effuse more slowly than helium.
To find the number of N2O4 molecules, we first need to calculate the number of moles of N2O4 in 76.3g using the molar mass. We divide 76.3g by 92.02 gmol to find 0.83 mol. Next, we use Avogadro's number, 6.022 x 10^23 molecules/mol, to convert moles to molecules. Multiplying 0.83 mol by Avogadro's number gives us approximately 5 x 10^23 molecules of N2O4 in 76.3g.

The notation "gmol⁻¹" refers to grams per mole, which is a unit of measurement used in chemistry to express the molar mass of a substance. It indicates how many grams of a substance are contained in one mole of that substance. For example, if a compound has a molar mass of 18 gmol⁻¹, it means that one mole of that compound weighs 18 grams. This unit is essential for converting between the mass of a substance and the amount of substance in moles.
