Final answer:
To find how long it would take to distribute one Avogadro number of grains at a rate of 10¹° grains per second, divide Avogadro's number by the distribution rate, which equals 6.02 × 10±³ seconds. The correct answer is C.
Step-by-step explanation:
The student is asking about Avogadro's number, which is a constant used in chemistry representing the number of particles (atoms, molecules, etc.) in a mole. It is equivalent to 6.02 × 10²³ particles. To determine how much time it would take to distribute one Avogadro number of wheat grains at a rate of 10¹° grains per second, we divide Avogadro's number by the distribution rate:
Total Time (seconds) = Avogadro's number / distribution rate
Total Time (seconds) = 6.02 × 10²³ / 10¹°
Total Time (seconds) = (6.02 × 10²³) / (10 × 10¹)
Total Time (seconds) = 6.02 × 10²³ / 10±°
Total Time (seconds) = 6.02 × 10±³
Therefore, the correct answer is C, 6.02 × 10±³ seconds.
