Answer :
To determine which item has the greatest mass from the given options, we need to compare the masses of each:
1. Grain of salt: [tex]\(6.5 \times 10^{-2}\)[/tex] gram
2. Grain of sand: [tex]\(2.6 \times 10^{-3}\)[/tex] gram
3. Dust particle: [tex]\(7.0 \times 10^{-10}\)[/tex] gram
4. Grain of rice: [tex]\(2.8 \times 10^{-2}\)[/tex] gram
Let's interpret these scientific notation numbers:
- [tex]\(6.5 \times 10^{-2}\)[/tex] means 0.065 grams.
- [tex]\(2.6 \times 10^{-3}\)[/tex] means 0.0026 grams.
- [tex]\(7.0 \times 10^{-10}\)[/tex] means 0.0000000007 grams.
- [tex]\(2.8 \times 10^{-2}\)[/tex] means 0.028 grams.
Now, we compare these numbers to see which one is the biggest:
- 0.065 (for grain of salt)
- 0.0026 (for grain of sand)
- 0.0000000007 (for dust particle)
- 0.028 (for grain of rice)
From this comparison, we can see that 0.065 is the greatest among these values.
Therefore, the item with the greatest mass is the grain of salt.
1. Grain of salt: [tex]\(6.5 \times 10^{-2}\)[/tex] gram
2. Grain of sand: [tex]\(2.6 \times 10^{-3}\)[/tex] gram
3. Dust particle: [tex]\(7.0 \times 10^{-10}\)[/tex] gram
4. Grain of rice: [tex]\(2.8 \times 10^{-2}\)[/tex] gram
Let's interpret these scientific notation numbers:
- [tex]\(6.5 \times 10^{-2}\)[/tex] means 0.065 grams.
- [tex]\(2.6 \times 10^{-3}\)[/tex] means 0.0026 grams.
- [tex]\(7.0 \times 10^{-10}\)[/tex] means 0.0000000007 grams.
- [tex]\(2.8 \times 10^{-2}\)[/tex] means 0.028 grams.
Now, we compare these numbers to see which one is the biggest:
- 0.065 (for grain of salt)
- 0.0026 (for grain of sand)
- 0.0000000007 (for dust particle)
- 0.028 (for grain of rice)
From this comparison, we can see that 0.065 is the greatest among these values.
Therefore, the item with the greatest mass is the grain of salt.
