Question

Edgar used a balance to determine that the mass of a specimen was 0.00063 kg. He collected 6 specimens of the same size. What is the total mass of all 6 specimens, written in scientific notation?

Answer 1

Final Mass of 6 specimens is 3.78 * 10⁻³ Kg

Answer 2

Here, Mass of one specimen = 0.00063 = 6.3 * 10⁻⁴
Now, Mass of 6 specimens = 6.3 * 10⁻⁴ * 6
= 37.8 * 10⁻⁴ = 3.78 * 10⁻³

In short, Your Answer would be: 3.78 * 10⁻³ Kg

Hope this helps!
