單項選擇題假定空氣中的氧為溶質(zhì),氮為惰性氣體,它們的體積比為1:4,若視空氣為理想氣體,則氧在空氣中的摩爾分數(shù)、比摩爾分數(shù)、質(zhì)量分數(shù)以及比質(zhì)量分數(shù)數(shù)值的大小順序為()

A.比質(zhì)量分數(shù)<比摩爾分數(shù)<質(zhì)量分數(shù)<摩爾分數(shù)
B.比質(zhì)量分數(shù)>比摩爾分數(shù)>質(zhì)量分數(shù)>摩爾分數(shù)
C.比摩爾分數(shù)<比質(zhì)量分數(shù)<質(zhì)量分數(shù)<摩爾分數(shù)
D.比摩爾分數(shù)>比質(zhì)量分數(shù)>質(zhì)量分數(shù)>摩爾分數(shù)
