WebMass percent composition (also called mass percent or percent composition) is the easiest way to express the concentration of a solution because no unit conversions are required. … WebStep 5: Solve for x. Since the concentration value cannot be negative, we take up the positive value of x. In other words, the value of x that makes chemical sense is taken. x 2 + x -6 = 0 The equation gives x = 2 or x = -3. Step 6: Calculate the values of equilibrium concentration for each substance using the value of x. Thus, we have
