Part 2: A solution containing 4.5 g of an unknown molecular solute dissolved in 125 g of water boils at 100.103°C. What is the molecular mass of the solute?

b.

the accuracy of the data.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

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.
