<u>Answer:</u> The molarity of stock solution of luminol is 1.055 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
Given mass of luminol = 14.0 g
Molar mass of luminol = 177 g/mol
Volume of solution = 75.0 mL
Putting values in above equation, we get:
Hence, the molarity of stock solution of luminol is 1.055 M
The atomic symbol that could represent an isotope that undergoes radioactive decay to produce Pb-206 would be 238/92 U.
