Scientists recently discovered that firing low-energy particles at potatoes keeps the potatoes from developing unwanted sprouts. They observed that these energy particles prevent cell
division in the sprouts. This stops the potatoes from sprouting for up to 120 days. How will this
development most likely affect the potato industry?

By allowing the potatoes to be stored longer so they can be sold during winter months.

Explanation:

Since low energy particles are fired at the potatoes to prevent them from developing unwanted sprouts, it means that it prevents sprouts from growing on the potatoes.

Now, winter is wet period which encourages more growth of the sprouts. Thus, the way this development will affect the industry is that the potatoes will be stored for longer period and then sold in the winter.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
