We can calculate the total mass of the clips in the box by multypling the amount of paper clips in the box and the individual mass.
The box contains 5.5 * 10^3 paper clips.
The mass of each paper clip is 4 * 10^(-4) kg.
So we can write:
[tex]\begin{gathered} M=n\cdot m \\ M=(5.5\cdot10^3)\cdot(4\cdot10^{-4})=(5.5\cdot4)\cdot10^{3-4}=22\cdot10^{-1}=\frac{22}{10}=2.2 \end{gathered}[/tex]Answer: The total mass of the paper clips in the box is 2.2 kilograms.
