THE ANSWER IS: <u>737.5</u>
I JUST TOOK THE QUIZ!!!!
There can only be two electrons in the innermost shell of an atom so b is the correct answer
No it is redistributed and the state changes to gas and liquid
The molarity of the zinc chloride solution will be 0.089 M
<h3>Molarity</h3>
Mole of 7.24 g ZnCl2 = 7.24/136.286 = 0.5312 mol
Total volume of water used in preparing the solution = 300 + 300 = 600 mL
Molarity of the solution = mole/volume = 0.5312/0.6 = 0.089 M
The molarity of the zinc chloride solution is, therefore, 0.089 M
