You can see how this formula works reading the example above or/and choosing another one at the bottom of this page. That is exactly the formula that we use in this calculator. F 50 4 Diffusion and Mass Transfer Definition of diffusion : Diffusion. M kg v m³ = m lb v gal × mcf vcf, but m kg v m³ is, by definition, the density (d) in kg/m³, soįinally, we can generalize this formula any units of mass and volume, since we know how to find the values for mcf and vcf (Check the factor tables below). Vapour pressure data : n - butane, Psia n - hexane, Psia 20 1.5 70 32 Temp. Now, dividing the equation (1) by the equation (2), we get Volume in cubic meters = volume in gallons × vcf or We will call 0.003785411784 the volume conversion factor - vcf To transform the volume from gallons to cubic meters we should multiply the volume in cubic meters by 0.003785411784. Mass in kilograms = mass in pounds × mcf or We will call 0.45359237 the mass conversion factor - mcf To transform the mass from pounds to kilograms we should multiply the mass in pounds by 0.45359237. If we have, for example, mass in pounds and volume in gallons, we should do something to correct our result. For example, mass in kg and volume in liters. Effects on body weight are common during intermediate-duration exposure of rats to n-hexane and tend to occur prior to the development of neurotoxicity (see. It can be used widely as a relatively safe, largely unreactive, cheap, and easily evaporated non-polar solvent. It is an odorless and colorless liquid, when pure, and it has a boiling point of approximately 69 C (156 F). But this works fine when the density value we have (from a chart for example) is defined using the same unit of volume and mass that we will use in the formula. Hexane is an organic compound, a straight-chain alkane with six carbon atoms with the molecular formula C6H14. Very simple isn't it? Yes, it is as simple as that. Molecular weight is actually an older term of relative molar mass or molecular mass, which is a dimensionless quantity equal to the molar mass divided by the molar mass constant defined by 1 g/mol. Mass = density × volume = 750 × 2 = 1500 Kg The exact term of the above molecular weight is molar mass, which is based on the atomic mass of each element. Plugging the values in the formula, we get Well, by definition of density we just need to use the formula:Įxample: How much does 2 cubic meters of gasoline weigh in kilograms if the gasoline density is 750 kg/m³?
