A gas mixture contains each of the following gases at the indicated partial pressures: N2, 231 torr ;
O2, 101 torr; and He, 155 torr.

Part A: What is the total pressure of the mixture?

Part B: what mass of each gas is present in a 1.00 - L sample of this mixture at 25.0 celsius?

if you mean hydrogen and oxygen then water is the product

idk what is it? is this a question that you know the answer or u dont

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.
