Question

1) A box contains 5.5 x 103 paper clips. The mass of each paper clip in the box is 4 x 10-4 kilograms. What is the total mass of the paper clips in the box?

Answer 1

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:

`\begin{gathered} M=n\cdot m \\ M=(5.5\cdot10^3)\cdot(4\cdot10^(-4))=(5.5\cdot4)\cdot10^(3-4)=22\cdot10^(-1)=(22)/(10)=2.2 \end{gathered}`

Answer: The total mass of the paper clips in the box is 2.2 kilograms.
