Una mezcla de cuso4: 5h20 y mgso4 7h2o se calienta hasta que se elimina toda el agua. si 5.020 g de la mezcla produjeron 2.988 g de las sales anhidras, cuál es el porcentaje de cuso4.5h2o en la mezcla?

i dont know the answe

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.
