1. The problem asks for the mass of 3 servings. 2. To find the total mass, we need to know the mass of one serving. 3. Let the mass of one serving be $m$. 4. The total mass for 3 servings is calculated by multiplying the mass of one serving by 3: $$\text{Total mass} = 3 \times m$$ 5. Without the value of $m$, we cannot find a numerical answer. 6. If you provide the mass of one serving, I can calculate the total mass for 3 servings.
