Which has the greatest mass?

A. Grain of salt: [tex]6.5 \times 10^{-2}[/tex] gram

B. Grain of sand: [tex]2.6 \times 10^{-3}[/tex] gram

C. Dust particle: [tex]7.0 \times 10^{-10}[/tex] gram

D. Grain of rice: [tex]2.8 \times 10^{-2}[/tex] gram

Answer :

To determine which item has the greatest mass, let's compare the masses provided:

1. A grain of salt has a mass of [tex]\(6.5 \times 10^{-2}\)[/tex] grams, which is 0.065 grams.
2. A grain of sand has a mass of [tex]\(2.6 \times 10^{-3}\)[/tex] grams, which is 0.0026 grams.
3. A dust particle has a mass of [tex]\(7.0 \times 10^{-10}\)[/tex] grams, which is 0.0000000007 grams.
4. A grain of rice has a mass of [tex]\(2.8 \times 10^{-2}\)[/tex] grams, which is 0.028 grams.

Comparing these values:

- 0.065 grams (grain of salt)
- 0.0026 grams (grain of sand)
- 0.0000000007 grams (dust particle)
- 0.028 grams (grain of rice)

The grain of salt, with a mass of 0.065 grams, has the greatest mass among the items listed.
