Consider the following equilibrium for the decomposition of cyclohexane (CH14) to produce benzene (CH) and hydrogen gas: CH14(g) = CH (8) + 4 H2(g)
6
Suppose 0.500 atm of cyclohexane is initially present in a sealed chamber. At equilibrium, the partial pressure of benzene is 0.100 atm. What is K? Round your answer to
the 0.0001 place.

the grams   of   barium that   are in   2.3 x 10^23   atoms of barium   is   52.4 g (answer c)

    calculation

mass = moles   of ba   x molar   mass of ba

  molar mass of ba from periodic table=   137.3 g/mol

  use the   avogadro's law   constant   to   calculate the moles of barium

  that   is     1 mole =   6.02   x 10^23 atoms

                    ? moles = 2.3 x 10^23   atoms

by cross   multiplication

=(1 mole   x 2.3x 10^23 atoms)   / 6.02   x10^23 atoms)=   0.382   moles

mass   is therefore = 137.3   g/mol x 0.382 mol = 52.4 ( answer c)
