A box contains 5 x 10^3 paper clips. The mass of each paper clip is the box is 8 x 10^-4 kilograms. What is the combined mass of the paper clips in the box? A. 4 kg B. 4 x 10^7 kg C. 4 x 10^-7 kg D. 40 kg

Respuesta :

In this case, we'll have to carry out several steps to find the solution.

Step 01

Data:

# paper clip = 5x10^3

m paper clip = 8x10^-4

total m paper clips = ?

Step 02:

total m paper clips = # paper clip * m paper clip

[tex]\text{total = 5}\cdot10^3\cdot8\cdot10^{-4}=\text{ 40}\cdot10^{(3-4)}[/tex][tex]\text{total = 40.10}^{-1}[/tex]

The answer is:

total mass of paper clips is 4 kg.
