Answer :
To determine which item has the greatest mass, we will compare the given masses for each item. Here are the masses:
1. A grain of salt: [tex]\(6.5 \times 10^{-2}\)[/tex] grams
2. A grain of sand: [tex]\(2.6 \times 10^{-3}\)[/tex] grams
3. A dust particle: [tex]\(7.0 \times 10^{-10}\)[/tex] grams
4. A grain of rice: [tex]\(2.8 \times 10^{-2}\)[/tex] grams
Now, let's compare these values:
- [tex]\(6.5 \times 10^{-2}\)[/tex] grams is equivalent to 0.065 grams.
- [tex]\(2.6 \times 10^{-3}\)[/tex] grams is equivalent to 0.0026 grams.
- [tex]\(7.0 \times 10^{-10}\)[/tex] grams is equivalent to 0.0000000007 grams.
- [tex]\(2.8 \times 10^{-2}\)[/tex] grams is equivalent to 0.028 grams.
When we compare these decimal numbers, 0.065 is the largest value.
Therefore, the item with the greatest mass is the grain of salt, which has a mass of 0.065 grams.
