Question

a mustard seed has a mass of about 0.002 gram. a glass jar contains about 4.3602 x 10^4 seeds.

which is a reasonable estimate of the mass of the mustard seeds in the jar?

Answer 1

To estimate the mass of the mustard seeds in the jar, you can multiply the number of seeds by the mass of each seed.

Given:
- Mass of one mustard seed = 0.002 grams
- Number of seeds = \( 4.3602 \times 10^4 \)

Now, we can calculate the total mass:

\[
\text{Total mass} = \text{Number of seeds} \times \text{Mass of one seed}
\]
\[
\text{Total mass} = 4.3602 \times 10^4 \times 0.002
\]

Calculating this:

\[
= 4.3602 \times 0.002 \times 10^4 = 0.0087204 \times 10^4 = 872.04 \text{ grams}
\]

So, the total mass of the mustard seeds in the jar is approximately 872 grams.

A reasonable estimate of the mass of the mustard seeds in the jar would be **around 870 grams.**
