Answer:
16.06 L was the initial volume of the balloon.
Explanation:
Initial moles of freon in ballon =
Initial volume of freon gas in ballon =
Moles of freon gas added in the balloon = n = 3.50 mole
Final moles of freon in ballon =
Final volume of freon gas in ballon =
Using Avogadro's law:
( at constant pressure and temperature)
16.06 L was the initial volume of the balloon.
The average atomic mass of Boron: 10.431 amu
<h3>Further explanation </h3>Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is the average atomic mass of all its isotopes
In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu
Mass atom X = mass isotope 1 . % + mass isotope 2.% + ...
The average atomic mass of boron :
