n-pentane and cyclopentane mass concentration
type: Concept
Object Of Interest: n-pentane
Object Of Interest: cyclopentane
Observation Matrix: gas phase
definition: Mass concentration means mass per unit volume and is used in the construction mass_concentration_of_X_in_Y, where X is a material constituent of Y. A chemical species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. n-pentane and cyclopentane is a mixture of two compunds and belongs to the group of alkanes.
