The ideal gas law is a rearrangement of which of the following gas laws? boyle's law charles's law avogadro's law all of the above

The answer is All of the above. The rearranged law incorporates Charles Law about the relationship between the volume and temperature of an ideal gas  with Boyles law that stipulates the relationship between pressure and volume of an ideal gas. Avogadro principle strengthens on this formula by applying the standard of the number of atoms in a mole of gas.(P1*V1)/T1 = (P2*V2)/T2

where:

V is the volume
P is the pressure
T is the temperature measured in kelvin
k is a constant (with units of energy divided by temperature)

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
