How many grams of Na SO, would be dissolved in 1.50 kilograms of water to make a solution that is 0.5m? (Answer should be rounded to 2 decimal
places.) *

43.452

step-by-step explanation:

284 times .153 = 43.452

28528289 29823282 8298232 39858

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.
