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

the answer is mabye 30 I didnt understand
Answer:
the third one The orange color one
Explanation:
) Copper density= 8.96 g/cm³ Copper volume= 51.3c.m.3 Copper density = M/V8.96= M/51. M= 459.68g.m.
