Molar size
A molar quantity is a physical or chemical quantity that depends on the amount of substance or the number of particles . The advantage of molar sizes (e.g. mass, volume, etc.) compared to their non-molar counterparts is that they are independent of the quantity of the substance and thus easier to tabulate. A molar quantity is an intensive state quantity , which is why it is mostly used to formulate intensive state equations .
In the case of mixed phases , partial molar quantities are also used , which only refer to the amount of substance of a single component , e.g. B. the partial molar volume . Molar sizes can also be differentiated according to substance- specific and system-specific sizes .
