Given the following densities: The density of corn syrup is ~1.4 g/mL, water is ~1.0 g/mL, and mineral oil is ~0.8 g/mL. The density of a marble is ~3.5 g/mL, a rubber stopper is ~1.2 g/mL, ice is ~0.92 g/mL, and a cork is ~0.2 g/mL. Identify L1 , L2 , S1 , S2 , S3 , and S4 in the tall glass cylinder. IM SO LOST?!

the answer would be c

b.

the accuracy of the data.

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.
