Electrical engineers are the scientists that study the production of electricity more efficient.
<h3>
Which type of scientist would study how electricity could be produced more efficiently?</h3>
Electrical engineers are the type of scientist that would most likely study how electricity could be produced more efficiently because they produced new technologies which are cost efficient as well as produce high amount of electricity.
So we can conclude that electrical engineers are the scientists that study the production of electricity more efficient.

Answer:
Molarity = 0.154 M
Explanation:
Given data:
Volume of solution = 8.42 × 10² mL ( 8.42 × 10² /1000 = 0.842 L)
Mass of potassium iodide = 22.4 g
Molarity of solution = ?
Solution:
Number of moles of potassium iodide:
Number of moles = mass/molar mass
Number of moles = 22.4 g/ 166.0 g/mol
Number of moles = 0.13 mol
Molarity:
Molarity = number of moles / volume in L
Molarity = 0.13 mol / 0.842 L
Molarity = 0.154 M
