[求助] MS中怎么看浓度

我用DPD算了一个gemini表面活性剂的cmc。参数如下
comment: Generating content of simulation box from gemini.Dpd_par file
comment: Suggesting that 36 beads are 'gemini' beads
comment: Suggesting that simulation contains 3 copies of the gemini molecule
comment: Suggesting that 2971 beads are 'water' beads
comment: Suggesting that simulation contains 2971 copies of the water molecule
comment: Calculated that the total number of beads should be 3007.
comment: Inserting 3007 beads
comment: Box density is calculated as 3.007000

Simulation Parameters
---------------------

parameter: sizeX, sizeY, sizeZ       = 10.00 10.00 10.00
parameter: Total no. of beads        = 3007
parameter: No. of molecule types     = 2
parameter: Density                   = 3.01
parameter: Temperature (kT)          = 1.0000
parameter: Dpd timestep              = 0.050
parameter: Rcut for Fd and Fr forces = 1.000
parameter: Universal spring constant = 4.000000
parameter: Shearing (along x)        : off
parameter: Walls                     : off


刚开始设定relative amount的值是活性剂:水=1:100
不知道整个系统的浓度mol/L怎么求?

希望大神帮忙啊
