Electrolytes are important to the body because they contribute to basic functions such as
muscle contraction. Electrolyte ions, such as sodium and magnesium, must be balanced
correctly in order to maintain bodily functions.
What property of water allows it to act as carrier for these ions?
A Polarity
BViscosity
C Shape
D Density

56 moles of   lieter in chemistry

fe 55.85 g/mol and h2o 18.02 g/mol.

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.
