Addressing a mass value at time 0

Hello everyone, I am trying to create a plot of mass at time t over mass at time 0. I have defined a non-local coupling integration for the domain I am interested at, and for mass at time t I have the expression m(t)=intop1(c)*MW where c is concentration and MW is molecular weight. I am wondering if there is a way to do something similar or to define a variable that can hold the value of the mass ONLY at time 0.
