Answer: sorry I cant help you I need the same answer
Explanation:
No of Neutrons =Mass No-No of protons


- Hence it has atomic no 38
The element is Stroncium(Sr)
To solve this we use the
equation,
<span> M1V1 = M2V2</span>
<span> where M1 is the
concentration of the stock solution, V1 is the volume of the stock solution, M2
is the concentration of the new solution and V2 is its volume.</span>
<span>2.0 M x V1 = 0.50 M x 200 mL</span>
<span>V1 = 50 mL needed</span>
