The law of conservation of mass leads to what is called a mass or a material balance. Mass In = Mass Out + Mass Stored Raw Materials = Products + Wastes + Stored Materials. m R = m P + m W + m S (where (sigma) denotes the sum of all terms). m R = m R1 + m R2 + m R3 = Total Raw Materials. m P = m P1 + m P2 + m P3
