(Scientific Notation in the Real World MC) The mass of a paperclip is 6.0 × 10−4 mg. If a box of paperclips has 7.23 × 104 paperclips, determine the total mass of the paperclips in the box. Write the final answer in scientific notation with the correct number of significant digits.

1. 4.338 × 101 mg

2. 4.3 × 101 mg

3. 4 × 101 mg

4. 3.62 × 100 mg



Answer :

The total mass of the paperclips in the box will be A. 4.338 × 10

How to illustrate the information?

It should be noted that from the information, the mass of a paperclip is 6.0 × 10−4 mg and a box of paperclips has 7.23 × 104 paperclips.

Therefore, the total mass of the paperclips in the box will be:

= (6.0 × 10^-4) × (7.23 × 10⁴)

= 43.38

= 4.338 × 10

Therefore, the total mass of the paperclips in the box will be 4.338 × 10.
