| Term (EN) | molar composition |
|---|
| Definition (EN) | gas composition expressed as a molar (or mole) fraction, or molar (mole) percentage
NOTE The mole fraction, x, of component i is the quotient of amount of substance of this component and amount of substance
of the whole mixture. The unit of amount of substance is mole. The mass of one mole of any chemical species, in grams, is
numerically equal to its relative molecular mass. A table of recommended values of molar masses is given in ISO 6976. For an ideal
gas, the mole fraction is identical to the volume fraction, but this relationship cannot in general be assumed to apply to real gas behaviour

| Term (BS) | molarni sastav |

| Definition (BS) | sastav gasa izražen kao molarni (ili molski) udio, ili molarni (molski) procenat
Napomena 1 uz termin: Molski udio, x, komponente i je količnik količine supstance ove komponente i količine supstance u cijeloj
smješi. Jedinica količine supstance je mol. Masa jednog mola bilo koje hemijske vrste, u gramima, brojčano je jednaka njenoj
relativnoj molekularnoj masi. Tabela preporučenih vrijednosti molarnih masa je data u ISO 6976. Za idealan gas molski udio je
identičan zapreminskom udjelu, ali se ne može generalno pretpostaviti da se ovaj odnos primjenjuje na ponašanje pravog gasa. |
