As shown in the figure: what is the difference between the fraction and the standard volume fraction? Seeking advice
The fraction generally refers to the proportion of a certain component within the whole, and can be volume fraction, mass fraction, etc., depending on the specific context. The standard volume fraction specifically refers to using the volume under standard conditions (usually referring to standard temperature and pressure, namely 0°C and 1 atmosphere) as the basis for calculating the ratio. In other words, the standard volume fraction takes into account the effects of temperature and pressure on volume, allowing for a fair comparison of data under different conditions. In simple terms, a fraction is a broad concept, while the standard volume fraction is a type of fraction that emphasizes the volume ratio under standardized conditions. .
Why is there such a large difference between molar fractions and volume fractions?
Because the molar masses of the components do not differ greatly
Should the standard volume fraction and the molar fraction be the same?
