Step-by-step explanation:
The mass of the salt grain is 0.0006 grams, which can be written in scientific notation as 6 x 10^-4 grams.
To compare the masses of the salt and sand grains, we need to express the mass of the sand grain in scientific notation as well.
The mass of the sand grain is 0.009 grams, which can be written in scientific notation as 9 x 10^-3 grams.
Comparing the two masses in scientific notation, we can see that:
6 x 10^-4 < 9 x 10^-3
Therefore, the sand grain is heavier than the salt grain
Answer:
Step 1. Move the decimal place to the right to create a new number between 1 and 10.This gives N=3.Step 2. Count the number of times you moved the decimal.You moved the decimal 8 places to the right.That means the exponent a=-8.Step 3. Write the number in scientific notation.0.000 000 03 g=3×10-8lg
