II. The student then takes a 1.00 M stock solution of table sugar (sucrose, C12H22011) and mixes 0.305 L of stock solution with additional
distilled water to create a dilute solution with a total volume of 1.25 L.
• Explain how the student can determine the molarity of the resulting
solution. Show a valid calculation for the final molarity.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
