When cookies are made, the ingredients are added in precise measurements to create the cookie dough. Once the dough is mixed it is baked at a precise temperature for a specific amount of time. Deviation from the recipe can result in cookies that could be underbaked, overbaked, or that just don't taste good at all. What types of conditions could change the outcome of the recipe? Would it be possible to reverse the chemical reaction that took place when the cookies were baked?

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)
