What is the molarity of a NaOH solution if 25.0 mi is required to completely neutralize 40.0 ml of a 1.5 M solution of H2SO4?

2b2t

explanation:

2b2t

ok whats the question if not i cannot you i need question and need a thing to answer

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.
